Claudio,

Sorry I confused you with my typo.

At 03:54 PM 7/1/2003, you wrote:
I don't get the Procedural one. In your msg you've said "write XML at home and convert it into HTML". I think from this excerpt that you mean that instructions can be kept and run inside an XML file. I still don't get how. I only associate the process to de XSL language, providing an HTML output.

No, you're correct -- typically the instructions on how to get HTML out of XML will be kept outside the XML.


(Although to be complete, it should be mentioned that Architectural Forms-like techniques can be used to bind such "instructions" "within" the XML; in any case you'll still need some kind of external application to do the conversion.)

Don't make the mistake of assuming, however, that this architecture requires XSLT. There are many ways (as Jonathan R. has recently reminded us) of converting XML to HTML, such as Perl, Python or whatever. They're just not in scope for this list.
:->


This is why I asked David to let me know where on earth I can find a conceptual model of the whole architecture.

It still puzzels me how the data-process-presentation three tiered layout is kept with all this tools/languages/transformations/schemas.

Conceptual architecture:


 XML           -->   XSLT engine       --> output (HTML, PDF etc.)
  ^ validation        ^ transformation
 schema              stylesheet

My only point is that the middle piece doesn't have to happen in a server or a client: it can be standalone and run on the XML source in batches.

Another point of confusion is that the middle part doesn't actually have to be XSLT, though XSLT excels at this role (since it was designed for it).

Cheers,
Wendell
