binaries in xml schema?

[xml]

Knowing that the data format will be used to store binaries anyway in
embedded markets, I have to wonder if there is a formalized way to solve
the problems in embedding binary in XML documents.  Because it is going to
happen... there can't be any question about that.

I understand that a schema mechanism is being added to XML.  I don't know
anything about it... haven't been able to find anything yet.  But, if a  
schema is available in the file with the XML datasets, several binary datatypes
should be able to be called out.  This would make the MIME-happy folks happier
and help us build xml-compliant consumer electronic blocks that are affordable.

The concept of binary data in XML files has been brought up before countless
times and seems to be a hot topic.  The XML-server folks don't like it 'coz
well... their platform may have half a gigabyte of RAM to play with.  The 
client guys tend to stay quiet 'coz they know better... we're working with
platforms that span the range of products from Tamagotchi to Win32.  We have
to be careful with memory utilization and also need the ability to execute
code directly out of a memory pool (in XML).

So... is there any public information about XML-Schema?  Any idea if one or
more binary formats is called out as a datatype within it?
