Class Summary

DeclScanner	Try to read the XQuery declaration.
XQueryAST
XQueryLexer	The XQuery/XPath lexical analyzer.
XQueryParser	eXist parses an XQuery expression in (currently) 4 phases: 1) lexical analysis in XQueryLexer 2) syntax analysis and construction of an intermediate AST (abstract syntax tree) in XQueryParser 3) analysis of the intermediate AST, and construction of the executable XQuery expression tree from the intermediate AST in XQueryTreeParser 4) static analysis of the final expression tree The grammar in XQuery.g corresponds to phase 2.
XQueryTreeParser	The tree parser: walks the AST created by XQueryParser and generates an internal representation of the query in the form of XQuery expression objects.
