I think the main reason for the problem is that an XSLT/XPath
program makes many references to names (of elements and attributes)
which do not have to be declared, so that using an incorrect name
is not an error (either static or dynamic), but rather results in
an XPath expression that simply selects nothing.
I guess no one would do that deliberately?
Yet the rec and implementations don't provide any error | warning
about it?
It would be nice if processors would have a debug mode in which XPath
expressions would be checked against a schema or DTD and give a warning when
some 'impossible' expression is encountered. Impossible meaning something that
never can give a non-empty result on valid documents. Probably just paths that
are illegal according to the schema.
