Yes, I recommend that, based on Roger's use-case, support for modularity is
included in XPath 3.1.

And to answer the question on the last quoted line:

There are some people that don't want to be bound XQuery or XSLT and prefer to
have XPath programs that can be immediately executed either standalone, or as
part of an XQuery program or (trivially included) as part of an XSLT program.

Creating XPath programs eliminates the "portability problem" between XQuery and
XSLT.
