The xml::xql module implements the xql (xml query language) proposal submitted to the xsl working group in september 1998. the spec can be found at: http://www.w3.org/tands/ql/ql98/pp/xql.html. most of the contents related to the xql syntax can also be found in the xml::xql::tutorial that comes with this distribution. note that xql is not the same as xml-ql!

the current implementation only works with the xml::dom module, but once the design is stable and the major bugs are flushed out, other extensions might follow, e.g. for xml::grove.

xql was designed to be extensible and this implementation tries to stick to that. users can add their own functions, methods, comparison operators and data types. plugging in a new xml tree structure (like xml::grove) should be a piece of cake.
