Comment 1 for bug 930157

ctest -R xquery_3_0
shows that:
- the following functions are still not implemented:
filter#2 fold-left#3 fold-right#3 function-lookup#2 map#2 map-pairs#3 parse-xml-fragment#1 unparsed-text-lines#1 unparsed-text-lines#2 has-children#0 nilled#0 path#0 path#1

- the following functions are in the fn namespace and according to the F&O 3.0 spec they should not be there:
parse-xml#2 partial-apply#2 partial-apply#3

So, fn:available-environment-variables appears as implemented.
