I am sorry but I disagree. The callers of these methods want to get both type
info (either just the name or a full XQType) and the nillable property from a
global declaration. Why make two calls for this, when the two calls make almost
the same work underneath? Maybe it doesn't make too much difference in the
overall query performance, but it's not good coding practice, IMO. I can rename
the methods to "getInfoFromGlobalElementDecl" if you think that makes them more
readable. And if in the future a new caller needs only the type info or only
the nillable info, we can add new methods that return just the needed info.
By the way, in validate.cpp line 207 and 268 there are calls to
getTypeInfoFromGlobalElementDecl() that look like noops to me, because they
just discard the returned XQType and do not raise any exception if the
declaration is not found. Do I miss something?
