No, XSLT does not allow it, but even more fundamentally, it is not
well-formed XML.

Since you are confused on this issue, it is unclear to me what you intend
".." to mean:
    o   parent of the "current node" ("current" is node selected by
        "//*[./@filename != '']")
    o   parent of the "context node" ("context" is node selected by

If you want the current node's parent, use this:

    select =
    "document('ShareWebUsers.xml')//person[id =

If you want the context node's parent, use this:

    select =
    "document('ShareWebUsers.xml')//person[id = ../@ownedby"/>]/ntname"

I hope this helps!
