RE: [xsl] Using keys when unique identifier is a multi node value

["M. David Peterson" <m.david@xxxxxxxxxx>]

Yeah, you will have to fix it but if you architect it correctly and
allow for the fact that you will be "indexing" on a unique identifier at
a later date then it wont be any where near the headache that it could
be if you don't. Ive got a solution that I think will help you achieve
your goal at hand while allowing for a simple fix in the future... but I
just finished  an early morning 2 hour solutioning/documenting that
solution session at which the 1 hour mark my body was making low
rumbling growns... within 15 minutes they became idle threats, and just
recently a war was declared... ive got it in a stand off at the moment
but I shouldn't press my luck.. give me 30 minutes before I am able to
get back to my computer...

Best regards,

<M:/>

Robert,

That is an excellent point.  I actually spoke with the developer who is
providing me with the XML on this.  That is something that will be
accounted
for on the next iteration of our xml serialization.  Unfortunately, that
also means I will have to go back and fix the xsl.

I don't think you want to use first and last name as unique identifiers.

  The chance of having two Bill Smiths is pretty high...

Why not just create a truly unique identifier and use that as your
key/@use?

<Attendance id="a12345">
