Update of /cvsroot/monetdb/pathfinder/compiler/sql
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv23940/sql
Modified Files:
lalg2sql.brg
Log Message:
Implementation for ``fn:node-name($arg as node()?) as xs:QName?'',
which forms the backbone of
- fn:name (),
- fn:local_name() and
- fn:namespace_uri ().
doc_access-operator now has another accessor ``doc_QName'',
which supports access to the QName. ``doc_QName'' is not supported
by the MIL translation, yet.
