Anyway, I highly respect the ConTeXt and LuaTeX's work.
But if Taco and Hans can :
- use a proper regexp library (like lrexlib?), not the silly lpeg
PEG are not silly at all. PEG *include* regex, but not viceversa,
and it seems to have the same power of  CFG, so you can build a parser
for
pratically anything
(and you can not do this with regex) .
Perhaps the reverse sentence has more sense: drop the "silly" (?) regex,
use
the new peg.
For what I know the reverse side of lpeg is that a file must be loaded in
memory completly.
Well, I don't like to know what kind of thing is superior ... micro
kernel is superior than monolithic kernel, but...
Wrong paragon .
...
From *mathematical*  point  of  view, the set of all regular languages
are a subset of PEG languages .
PEG are more powerful than  regex --it's not an opinion, it's a fact.
...
The key reason for this is, more people are familiar with regexp. so
if you can build a 100% compatible regexp module on top of lpeg in
ConTeXt, it will be ok, or even better...
We already have lua for simple string manipulation, and lpeg for other
stuffs .
Again we don't need regex .

- full support of xslt:)
why not xquery too? Are mkiv  supposed to be a full  xml processor ?
No. I mean the user can have an option to convert an xml (that is, a
context document) using (maybe external) xslt tool.
This won't be too difficult to implement ...
hmm, external tools call for platform /SO issue ...
Personally xsltproc in linux it's OK -- I don't need
an integration ,
I prefear separations of concerns.
...
...
A bit of xslt can be done with lpeg (and not regex),
a bit == far from all
It's enough for simple xml processing .
If you need more, are you sure that you are using  the right tool ?

Things might be a lot better...
and worse too .
Things are now a lot better than before ,IMMO .
it should be.
It is .
