These paragraphs seems to contradict. ConTeXt is useful if you use an
environment more than once, but there are no ready-to-use ConTeXt
environments.

I am not averse to rolling my own, I am just confused why, if environments
are so powerful and flexible (flexible meaning one can easily change things,
unlike document classes), there are no pre-rolled environments available. I
am thinking here of standardized thesis environments for universities, or a
nice letter environment to demonstrate the beauty of TeX.

XML is no target format for any TeX implementation.

Yes, I meant RDF. XML is a very important format. I find it odd that TeX can
generate PDF but cannot output simple XML. So in order to have a semantical
document I must write it in XML and then process it with ConTeXt? Is the
capacity there (through LuaTeX perhaps) to write an XML generator?

While I would expect the reasons for wanting XML output would be obvious, a
concrete example is that at least one journal is deprecating LaTeX because
it wants to archive all of its articles in XML.
