The documentation is indeed terrible.  This library is used by other
Schemes; we should see if we can steal their docs, if they are better.

However it's possible to use SXPath with the string syntax.  I seem to
recall there's code out there to do that.  We could incorporate into
Guile to just support the standard syntax.  I think the way forward here
is to improve Guile's sxpath documentation, fixing whatever interfaces
are needed, and adding the xpath->selector function.
