You probably already know this, but Mike Kay says in his XSLT book
that "in the very early drafts, the syntax for writing what are now
XPath expressions was also expressed in XML" -- so it might be
worthwhile to look at those "early drafts" if they're still available.

The single example (p. 33) he provides is an XML-syntax equivalent for
the XPath expression 'select=/book/author/first-name':

<select>
  <path>
    <element type="book">
    <element type="author">
    <element type="first-name">
  </path>
</select>

...definitely a bit more verbose.
