Binary XML Storage

A recent update on XML transmission has been the conversion of XML from being transmitted as text to a much optimized way of converting it to a compressed format and then transmitting('gzip' in this context is pretty well known) for reasons such as network bandwith since XML as text is pretty verbose.

What I have been imagining is why not always store XML in binary format and applications working on XML uncompress the XML.So much for saving storing space..but every 'bit' saved counts heee
