<DD>Perform type checking of an expression and its subexpressions. This is the second phase of
static optimization.
<p>This checks statically that the operands of the expression have
the correct type; if necessary it generates code to do run-time type checking or type
conversion. A static type error is reported only if execution cannot possibly succeed, that
is, if a run-time type error is inevitable. The call may return a modified form of the expression.</p>
<p>This method is called after all references to functions and variables have been resolved
to the declaration of the function or variable. However, the types of such functions and
variables may not be accurately known if they have not been explicitly declared.</p>
<p>If the implementation returns a value other than "this", then it is required to ensure that
the location information in the returned expression have been set up correctly.
It should not rely on the caller to do this, although for historical reasons many callers do so.</p>

<DD>Add a representation of this expression to a PathMap. The PathMap captures a map of the nodes visited

<p>The default implementation of this method assumes that an expression does no navigation other than
the navigation done by evaluating its subexpressions, and that the subexpressions are evaluated in the
same context as the containing expression. The method must be overridden for any expression
where these assumptions do not hold. For example, implementations exist for AxisExpression, ParentExpression,
and RootExpression (because they perform navigation), and for the doc(), document(), and collection()
functions because they create a new navigation root. Implementations also exist for PathExpression and
FilterExpression because they have subexpressions that are evaluated in a different context from the
calling expression.</p>
