I agree that these two particular functions should be dropped, but for a
different reason: they are redundant.  Their functionality can be
achieved by extracting the relevant components from the rdf:text literal
and then doing string comparison.

actually, strictly speaking the functions in the current version of the
specification are not in any namespace, because the document does not
define what "fn:" stands for.

This is actually a problem for all functions in section 4, not just the
functions in section 4.3.
I agree that we cannot just reuse the F&O namespace without coordinating
with XPath/XQuery.  I also do not really see any other namespace that
would be suitable for these functions.
So it is probably best to remove section 4, unless some last-minute
coordination action is going to get underway (which I anyway doubt would
be successful).

Best, Jos
