[xquery-talk] Unusual XPath syntax question

[G. Ken Holman]

Yes, "." is the same as "./." and the shorter version (to me) would 
be more suitable for legibility.  The shorter syntax already is being 
used in the select attribute, so I'm unclear what the author might be 
trying to gain with the longer syntax.
