What Is XEML?
XEML
is an XML based application programming paradigm based on a concept called
xnodes
.
xnodes
are xml nodes of programming
metadata
.
XEML
attempts to standardize application development in order to maximize programming:
- simplicity
- reusability
- development speed
- language portability
- platform independence

XNode Reference
What we have here is hardly documentation yet. Consider it a place holder
and some formatting experimentation until we have time to get this written.
