Yes, I think your situation is true for a lot of Cocooners; I have
tended
to use XSP because my "use cases" do not require specialised data
generation (as yours seems to) - its mostly just pulling data from a
DB
(see the other thread on this topic).  If I can avoid handcoded Java
for
this type of application, I will do so.

I agree XSLT works (I use and I like it) - but the point I picked from
the
article was the difficulty of working with a page designer who may know

HTML and now wants to incorporate dynamic elements in the page - the
argument goes that giving that person a whole language (be it XSLT or
a full-blown JXT) is really overkill (and leads to mixing of view with
model).

I do think its good to bring in opinions from people outside of the
"Cocoon 
bubble" - certainly Cocoon has always espoused SOC and we need to 
look at insights that suggest where there are "gaps" in the approach;
not
because we are academics [remember the article was written by someone
with very solid experience in website design and maintenance ] but
because 
we have an inherent drive to "make things better"!

My 2c, anyway.

I'm new to cocoon and JXTs so what I know is only what I have read on 
the website and what I've done so far with a cocoon app I've taken over

development of. I will make some general comments on the ideas you've 
raised.

I wouldn't get bogged down in the whole "purity" thing with whether or

not a template is a "true template". For me, the important thing is 
separation of concerns. As you point out, XSLT provides enough 
facilities in the specification to create the necessary contracts for 
separation of concerns. For me, it's the only templating system I need

and I choose it because it is a widespread cross-technology standard.

Being a cocoon newbie, I'm questioning the need to use XSPs because I 
see them as a way to loose many of the bonuses that come with OO in 
terms of using popular industrial tools like JavaDoc and Junit.
Although 
I started my web development career with ColdFusion, I'm not a big fan

of the tags and code mixture when it comes to creating a controller (in

the MVC sense) or writing business logic.

I'm thinking I'm probably gonna write all my apps using custom
generator 
classes and just ignore XSPs. But that's just me. Some would argue that

XSPs are easier and "more rapid" but I think they just create an extra

layer of maintenance in your java application. I've just taken over 
development of an existing cocoon app here at work so it looks like
I'll 
be writing XSPs in the short term, but they are not for me.

Generally, as far as your discussion goes, I don't like using
text-based 
templates anywhere near my business logic - ie, I don't like using the

templating facilities of JSP, XSP, ASP, PHP, or ColdFusion. My 
experience is mainly with PHP, and I tend to write in an OO way - using

the standards based DOM API to build up my content, and then I use an 
XSLT processor to orchestrate the view (with XSLT stylesheets). I think

this concept in general is very simple but it is a scalable one with 
easy maintenance.

(I've written a PHP framework (XML Application Objects) which is on
hold 
while I learn cocoon http://xao-php.sf.net ). Maybe when I get more 
experience with cocoon, I will port XAO as a set of cocoon generators.

As it stands, it's already easy for me to integrate XAO applications 
into coocoon as it is easy to pull untransformed content into the 
sitemap -- especially in the contenxt of aggregation. Same is true the

other way around. XAO can easily "consume" XML from a cocoon app with 
one line.

So yeah, all I need is the DOM standard for content generation, and the

XSLT standard for formatting.
