Summary: fn:collection("DOES-NOT-EXIST") does not fail
Initial Comment:
When the argument to fn:collection() is non existent patthfinder return the
empty sequence. I think this is incorrect. In the specs
(http://www.w3.org/TR/xpath-functions/#func-collection) the part on resolving
the name of the collection says:
This function takes an xs:string as argument and returns a sequence of nodes
obtained by interpreting $arg as an xs:anyURI and resolving it according to the
mapping specified in Available collections described in Section C.2 Dynamic
Context ComponentsXP. If Available collections provides a mapping from this
string to a sequence of nodes, the function returns that sequence. If Available
collections maps the string to an empty sequence, then the function returns an
empty sequence. If Available collections provides no mapping for the string, an
error is raised [err:FODC0004].
So in my opinion an error should be generated. We had a couple of cases where
an error would have been very handy for the user to find errors in queries.
