[xquery-talk] momentary recursion dyslexia

Thank you, David. That clarifies matters. 

For those interested in such things, the October, 2004 working draft was the
first WD to specify that "the last step in a path is allowed to return a
sequence of atomic values." Prior to that version, path expressions were
only allowed to return (possibly empty) sequences of nodes. Since the Mark
Logic content server is based on the earlier May, 2003 WD, its "not a node"
error report is consistent with the earlier spec. 

Galax claims to be compatible with the October, 2004 WD but nevertheless
reports that an atomic value in the leaf position is an error, which appears
to be inconsistent with that claim.
