so in other words XBIS is really streaming and is good for kind of 
applications that do not need XOM (or *OM*-like) APIs.

XBIS could potentially process unlimited amount of data so nux could not 
really compare.

that is different. i had impression that BNUX defines binary XML 
representation.

i was curious how different is BNUX from XBIS.

why did you decide not to use XBIS XML encoding?

what is missing or needs to be added?

those may be valuable insight for W3C XBC WG?
