100% XSLT for the front end (web) presentation layer, and 100% C#
classes for middle and backend layers.  It encapsulates a number of
important business objects and processes, hence making life for the
developer simpler...

I have made this 'argument' to Karl S. before regarding the usage of
XSL to create web pages. I have done and entire site this way and
while it was technically satisfying it is in no way easy to maintain
and it is yet another technology path the needs to be learned and
learned well: XSL is NOT easy if you want to code professionally in
it. It IS easy to use XSL but not well. ....

Its hard to measure maintainability... and if you are the only member of the team with sufficient XSLT skills to maintain transforms that you wrote, then perhaps its not the right choice for your team at this time.

However, if there is someone in the team with good CSS skills but
little existing programming knowledge, train them in XSLT by getting
them to sit next to you and create/maintain the transforms (good CSS
programmers will want to produce much cleaner  HTML, and they won't
tie themselves in knots trying to generate complicated hacked together
markup).  You can quickly answer any questions that arise (the ones
that normally stump new people for a while, like counting whitespace
text nodes) and steer them in the right direction of using templates.
Within a short period of time, sometimes days, you have a person who
is far more knowledgeable than those that raise concerns about the use
of XSLT (who usually just know xsl:value-of).

At that point the argument against using XSLT because of difficulty or
maintainability carries less weight because your have a
"less-experienced" programmer able to do the work.
