performance issues

I have a generic XSL stylesheet which I use to transform multiple 
documents. This stylesheet contains a great number of templates, some of 
which are only used once, on one particular type of source document.

If I have lots of templates all in one file like this, is it likely to 
cause any performance issues? Or are the templates only loaded as and when 
they are needed?


(I am processing with Apache::AxKit)



Likewise, if I set up a variable which is effectively a pointer to an 
external document via the document() function, like so:

<xsl:variable name = "testDoc" 
select="document('/www/xml/testDoc.xml')/root/>

Does this cause the processor to load the contents of the document into 
memory, or will it not actually do that untill I make a futher attempt to 
try and acces some information from this document like so:

<xsl:value-of select="$testDoc/item[@id = $id]/@name"/>
