[xsl] csv slows down transform

[Jonathan Kart <jkart@xxxxxxxxxxxx>]

Hi all,

I have 2 sample stylesheets to show you.  They are auto-generated, so 
please forgive the redundancy and other flaws.  My question is, what 
does the first stylesheet consistently run slower than the second.  For 
an xml doc of about 2500 'Contacts' this first sheet takes ~14 seconds, 
the second less than 1 second.  I swear the only difference is that one 
inserts quotes and commas around the data while the other does not.  
It's not a trick question i promise.  The time difference is 
substantial.  We're using the php libxml extension in a web environment 
under windows 200 server, and iis.

Thanks for any help, this is boggling my itty-bitty mind.
