Hi Piotr,

First, if you use TeXML, make sure you download the latest version,
1.25-devel. This version is very stable and robust, and has the
texml_con script, which converts directly from XML to PDF or whatever
format you require:

texml_con <any option you can use with texexec> infile

It will create a ConTeX file along the way, as its first step. So if
your file is modern_photo.xml, a file called modern_photo.tex will be
created. You could open the modern_photo.tex file and make small changes
on that file. However, if you need to do this, you should instead type:

texml.py -e -c modern_photo.xml modern_photo.tex

That will create a ConTeXt file, which you can then alter.

Of course, having to alter the ConTeXt file defeats the purpose of XML.
You should be able to convert directly from XML to PDF. What alterations
do you think you will have to make? 

I know XSLT stylesheets can get very complicated. This is often the
case, including when I convert XML to HTML. You could try converting in
steps, making a small manageble change on one document, and then making
a small manageable change and so on.

Let me know your results. Good luck!
