Re: [xsl] Keys with duplicates should be simple

1.  There is no source XML document provided.
2.  It isn't clear if any/all "a" element(s) must be a child of a
"person" element.
3.  What is "key table" ? I haven't heard of such thing.
4. No example of the wanted result (that should be produced when the
transformation is applied upon the specific provided source XML
document) is provided.
5. The xsl:key declaration name "person" is confusing, because what is
matched is an "a" element -- not a "person" element

This is obviously ambiguous and rather undefined.

To prevent (wrong) guesses to 1 - 4 above, please enter a
well-defined, unambiguous question.

Also, please, note that if the solution to a problem is unknown, it is
better *not* to provide any transformation code -- we know in advance
that this code doesn't solve the problem.
