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.
See Markup levels
>II)What is the difference between Binary XML and XML Serialization??
Same serialization principles but the endresult is more compact and
usually not readable by humans.
for a list of different "representations" in BML.
>I am quite confused on this topic why at all it is required ?
* 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
