Wheather or not I can use it to write a schema checker is something I
will consider when I feel like it.
You have some misconception about the ability of schema to do 100%
validation. It can't on every level, period! In fact between level
sets, all it can do is validate a range of parents vs. a range of
children. It can't validate a relationship between a single parent
and posible several children. So schema is whoafully inadequate alone.
To propagate all the possible permutations would make schema 100%
valid. It doesen't have that capability and never will. If all you
use is schema to validate your xml, you don't know xml..

Doesn't build a tree? Wtf are you drinking?

To start, it blows the doors off all parsers out there. It uses a
substitution method that exponentially gets quicker. It starts from
the inner xml blocks and works out. It takes data off right away
and builds a tree without waiting for parent closure. Its 100%
accurate because the logic is flawless. It works on a micro as opposed
to macro idiom. Its out of order with discrete cells. This is the
fastest possible method to parse xml. I'm suprised no one ever did
this before. Its on the level of a node model but it can easily
hone in on patterns and discard whats not necessary and filter.
All while using an examination method that exponentionally gets
quicker as the search progresses.

I wan't your promise that when this idea takes off that you won't
have any part of it and continue to bury your head in the sand.
