My article on “smart” use of XSLT within BizTalk appeared in BizTalk
Hotrod Issue 4
.  Once again, a great set of content thoughout this issue.

The article talks about the “why and how” of using a “straight”
XSLT approach with BizTalk – where your XSLT files reside directly on disk,
and not within map assemblies.  It discusses caching compiled XSLTs, and using
XSLT 2.0 via the Saxon libraries.  You can download the sample code and comment
over on the article’s Codeplex project.
