Scan Variable reference.
Implements parsing of two syntax structures:
Standard XPath syntax [36], for SP variables:
VariableReference ::= '$' QName
Finds a SP variable with the given name. If outside of a SP context, or variable with the given name doesn't exists, then error is returned.
Non-standard syntax - MySQL extension for user variables:
VariableReference ::= '$' '@' QName
Item, corresponding to the variable, is returned in xpath->item in both cases.
