Since the OP is a newbie, I hasten to add that simple cases of this are 
often handled with string-valued parameters, not node-trees, so you could 
say for example

saxon in.xml stylesheet.xsl name='robin' size='small'

and get the same effect. It's easy to do, requires a little less overhead, 
and (like the more complex solution) binds the values at run-time, when 
they're required.

It was also subsequently written:

But unfortunately, match patterns like match="Species[Extinct=$extinct and 
Genus_Name=$name]" aren't legal in XSLT 1.0 (no variable or parameter 
references allowed there), so you're back to the in-template conditional 
test....

Cheers,
