[INFOD-WG] Output from getmetadata is not defined. - action 233

[Dieter Gawlick]

Steve,

the output is precisely specified in the following documents:

http://www.w3.org/TR/xpath-datamodel/

and

http://www.w3.org/TR/xslt-xquery-serialization/

I think we have to add a foot note in the specifications; we - the INFOD 
group - not try to specify this.
