A little. In short, we want to have in Quanta a common DOM tree for source
and VPL (WYSIWYG) mode. Right now we have our own tree and there is the
KHTML DOM tree. This requires intensive synchronization between the two
whenever the document is modified in source or VPL mode. With KDOM we
wanted to solve this problem, and can you tell me if this will be possible?
What I was thinking is:
- parse the document with our own parser and create a KDOM based tree
- the KDOM tree nodes must be extensible (they should be able to hold extra
information)
- KHTML should be able to render directly this KDOM tree (for VPL mode)
- it should be possible to modify the tree from code, without regenerating
from scratch

Now if all the above will be possible even with this monolithic design, I'm
fine with it. Like Paulo said, we just want to have a KHTML and the
underlying DOM tree which will make developing WYSIWYG application easier,
without requiring extensive and ugly hacks.
