Subject Re: Simple XSL question
Date Tue, 05 Feb 2002 22:53:26 GMT
<xsl:import> and <xsl:include> are your friends when you start getting 
concerned about performance issues and want to do everything in one 
pass!  Of course though, if you generate one form of content, and then 
transform it to another form of content (say, xml->docbook->html) you 
are SOL. :(
