Detailed Description

Matches numeric literals that are of type xs:integer and has a specific value.

For example IntegerIdentifier(4) would match the former but not the latter operand in this expression: "4 + 5".

Parameters

expr	the Expression to be tested. This is guranteed to always be a non `null`, valid pointer.

Returns: true if expr matches as according to this ExpressionIdentifier, otherwise false.
