Binary in many cases means that the readability requirement is removed 
which means that the *same* information as in regular XMLtextual files 
may be packaged in other and more time / space efficient ways.

In some approaches the markup is removed and the schema is assumed to be 
implicitly present at both the readers and writers side and in other 
approaches such a mine (BML) markup plus datatyping is always present.

Same serialization principles but the endresult is more compact  and 
usually  not readable by humans.

See 
<http://openebxml.sourceforge.net/realization/components/bml/documents/BML-design.html>
for a list of different "representations" in BML.

* Performance: approx more that 8 times faster when going from stream to 
in memory representations
* Size: 10-80% or in some cases more.
* Smaller code libraries
* Easier to write parsers
