Yet another oddity here. If count(WebExtra) can be greater than 1, then
string-length(WebExtra) is going to give you the string-length of the first
WebExtra element under 1.0, but in 2.0 mode it's going to give you an error.
If you really want to test the string-length of the first WebExtra element
under 2.0 then you have to say so explicitly by writing
string-length(WebExtra[1]). This change was introduced because a lot of
people were writing such code by mistake - I don't know if that's the case
here, but given the questionable nature of the rest of the code, I would
look at it pretty carefully.
