Don't know - I'm not an author of original concept... Guess
Stefano could clear up this thing for us :)

No, not exactly. Example snippet:
<map:select>
<map:when>
<map:generate/>
</map:when>
<map:when>
<map:generate/>
</map:when>
<map:otherwise>
<map:generate/>
</map:otherwise>
</map:select>
<map:serialize/>
Try to convert to matchers - you will fail :)

I do not see how example from this page could be restated in matchers.
