The only extensions I plan to suggest are layered on top of XML, just
like all good XML compatible projects. In particular, I need efficient
and fine grained 'pointers' and delta overlay trees.

One reason I sometimes refer to Binary Structured XML (bsXML ;-)) as
'compressed' is to allude to the analogy of being able to 'uncompress'
the stream to examine in in text. This is completely similar to using
gzip or bzip2.
Note that initially and primarily, I am still going for a self-described
format that is completely equivalent to XML 1.0. This is different from
WML and comparisons to ASN.1 where some information is implied. I have
however been considering a 'compression' level that includes a standard
way to do versioned dictionary compression which makes sense for XML use
