Re: union vs. "or" vs. contains?

I don't know what happened with me and the list, but I missed the last 
few messages in this thread re: Ant.
Just to clarify my own intentions, I really don't want to rely on other 
tools (Any, Bash, etc.) for something that I believe should be handled 
in the XSLT code.
My current approach works perfectly fine, even if it theoretically 
means a performance hit (hopefully Mike will address that before too 
long).   So, user specifies the config parameter, which loads the 
appropriate config file, which has the attribute on which the main 
templates are conditioned.
