And of course once you compile it with a specific processor you lose
one of the best things about an XSL stylesheet: the ability to run it
on more than one processor.

Many XSLT processors can compile a (at least a main/primary)

to .NET IL code. Many years ago Sun provided such "XSLT compilation.

In this way a single application written in XSLT can be offered in
executable code and this is usually a significant part of the
technical protection of any software application.

What is still missing is the ability to compile a set/library of
stylesheets that can be used by a primary stylesheet at runtime.
Though there is not any provision in the W3 Spec how to do this for
XSLT (I think things are better for XQuery), a de-facto
standard/implementation would be extremely useful. Not only some
existing libraries such as FXSL, FunctX, ()one put here any EXSLT
*implementation*, although EXSLT is just a specification, and by
default the implementations are not in XSLT themselves) etc., would
benefit from easier deployment (say in browsers), but this will
stimulate authors to write more such libraries -- to the benefit of
the whole XSLT developers community.

I would welcome if EXSLT2 specifies a mechanism for run-time binding
between a main stylesheets and one or more compiled libraries of

Hi Folks,

Had an interesting discussion that I started on a Linkedin group,
but should
probably have started here.  I had originally asked the question
"can you
sell an XSLT?".  And by that I don't mean is it possible, but would
buy one.  What is the market for XSLTs as products?

The comments clearly indicated that people are willing to (and
actually do)
buy XSLTs.  They tend to come in two forms.  First, a specific
solution to a
specific task.  A key niche need.  Second, there is the idea of
XSLT as a
software platform.  XSLT as programming in Xml.  I've certainly
thought this
because I've been working with xml for so long that I *think* in
terms of
Xml (perhaps there is a 12 step program for this).  So XSLT to me
is the
java of Xml.  Of course no offense to java users, myself being one

The reason I brought this up is that while I've been involved in
open source
XSLT work as well as created innumerable ones for clients
individually, I
have lots of ideas about XSLTs as general products.

 Ken Holman of course highlighted a key component to this topic,
which is
obfuscation in order to protect intellectual property.   That would
be the
difference between open source and product solutions.

So I post these comments here wondering if you have thoughts on
this topic
as well.  Would love to hear them.
