+(* This module specifies the Paxos Commit algorithm. We specify only *)

+(* specification in the following ways. *)
+(* *)
+(* - As in the specification of module TwoPhase, and for the same *)
+(* reasons, we let the variable msgs be the set of all messages that *)
+(* have ever been sent. If a message is sent to a set of recipients, *)
+(* only one copy of the message appears in msgs. *)
+(* *)
+(* - We do not explicitly model the receipt of messages. If an *)
+(* operation can be performed when a process has received a certain set *)
+(* of messages, then the operation is represented by an action that is *)
+(* enabled when those messages are in the set msgs of sent messages. *)
+(* (We are specifying only safety properties, which assert what events *)
+(* can occur, and the operation can occur if the messages that enable *)
+(* it have been sent.) *)
+(* *)
+(* - We do not model leader selection. We define actions that the *)
+(* current leader may perform, but do not specify who performs them. *)
+(* *)
+(* As in the specification of Two-Phase commit in module TwoPhase, we have *)
+(* RMs spontaneously issue Prepared messages and we ignore Prepare *)

- <h2><a name="values">Ordinary Model Values</a></h2>
- <P>
-A model must specify the values of all declared constants.
-You will sometimes want to let a constant equal an unspecified value or a finite
-set of unspecified values. For example, the spec might have a
-constant <code>Proc</code> whose value
-represents a set of processes.
-You could just let a process be a number, substituting an ordinary value
- like <code>{1, 2, 3}</code>
-for <code>Proc</code> . However, a better way is to represent a process by a TLC
-<em>model value</em>. A model value is an unspecified value
-that TLC considers to be unequal to any value that you can express
-in TLA<sup>+</sup>. You can substitute the
- set <code>{p1, p2, p3}</code> of three model values
-for <code>Proc</code> . If by mistake you write an expression
-like <code>p+1</code> where the value of <code>p</code> is
-a process, TLC will report an error when it tries to evaluate that expression
-because it knows that a process is a model value and thus not a number.
-An important reason for
-substituting a set of model values for <code>Proc</code> is
-to let TLC take advantage of symmetry, as described <a href="#symmetry">below</a>.
-</P>
-
-<P>
-There is one particular TLA<sup>+</sup> specification idiom
-that requires you to substitute a model value for a defined operator.
-Here is a typical example of this idiom.
-<pre>
- NotANat == CHOOSE n : n \notin Nat
-</pre>
-It defines <code>NotANat</code> to be an arbitrary value
-that is not a natural number. TLC cannot evaluate this definition because
-it cannot evaluate the unbounded <code>CHOOSE</code> expression.
-To allow TLC to handle the spec, you need to substitute a model value
-for <code>NotANat</code> . The best model value to substitute for it
-is one named <code>NotANat</code> . You can do this with the
-<a href="advanced-page.html#override">Definition Override</a> section of
-the <a href="advanced-page.html">Advanced Options Page</a>.
-</P>
-
-
-
-<p>
-There are some uses of model values that
-can't be specified with the <a href="overview-page.html#what-is-model">What is the model?</a>
-section of the <A href="overview-page.html">Model Overview Page</A>.
-If you encounter such a problem, you can declare your own set of model values
-with the <A href="advanced-page.html#additional">Additional Definitions</a> section
-of the <A href="advanced-page.html"> Advanced Options Page</A> and then use them
-as ordinary values in expressions of the model.

+ <P>
+A model must specify the values of all declared constants.
+You will sometimes want to let a constant equal an unspecified value or a finite
+set of unspecified values. For example, the spec might have a
+constant <code>Proc</code> whose value
+represents a set of processes.
+You could just let a process be a number, substituting an ordinary value
+ like <code>{1, 2, 3}</code>
+for <code>Proc</code> . However, a better way is to represent a process by a TLC
+<em>model value</em>. A model value is an unspecified value
+that TLC considers to be unequal to any value that you can express
+in TLA<sup>+</sup>. You can substitute the
+ set <code>{p1, p2, p3}</code> of three model values
+for <code>Proc</code> . If by mistake you write an expression
+like <code>p+1</code> where the value of <code>p</code> is
+a process, TLC will report an error when it tries to evaluate that expression
+because it knows that a process is a model value and thus not a number.
+An important reason for
+substituting a set of model values for <code>Proc</code> is
+to let TLC take advantage of symmetry, as described <a href="#symmetry">below</a>.
+</P>
+
+<P>
+There is one particular TLA<sup>+</sup> specification idiom
+that requires you to substitute a model value for a defined operator.
+Here is a typical example of this idiom.
+<pre>
+ NotANat == CHOOSE n : n \notin Nat
+</pre>
+It defines <code>NotANat</code> to be an arbitrary value
+that is not a natural number. TLC cannot evaluate this definition because
+it cannot evaluate the unbounded <code>CHOOSE</code> expression.
+To allow TLC to handle the spec, you need to substitute a model value
+for <code>NotANat</code> . The best model value to substitute for it
+is one named <code>NotANat</code> . This is done in the
+<a href="advanced-page.html#override">Definition Override</a> section of
+the <a href="advanced-page.html">Advanced Options Page</a>. The Toolbox will
+create the appropriate entry in that section when it creates a model
+if it finds a definition having the precise
+syntax above or the syntax
+<pre>
+ NotANat == CHOOSE n : ~(n \in Nat)
+</pre>
+where <code>Nat</code> can be any expression, and <code>NotANat</code> and <code>n</code>
+can be any identifiers.
+</P>
+
+
+
+<p>
+There are some uses of model values that
+can't be specified with the <a href="overview-page.html#what-is-model">What is the model?</a>
+section of the <A href="overview-page.html">Model Overview Page</A>.
+If you encounter such a problem, you can declare your own set of model values
+with the <A href="advanced-page.html#additional">Additional Definitions</a> section
+of the <A href="advanced-page.html"> Advanced Options Page</A> and then use them
+as ordinary values in expressions of the model.

+
+<h2><a name="typed-values">Typed Model Values</a></h2>

+expression <code>p=2</code> where <code>p</code> is
+a process. If you substitute a set of ordinary model values for the set
+of processes, TLC will simply obtain the value <code>FALSE</code>
