Because you don't need to parse the XSD(s) ...
DTD's are required at the XML Parser level (in XML 1).

This proposal simplifies the XML Parser significantly.
If you add an XSD(or more) later it doesn't affect the XML because it is
entirely out-of-band (except when using an XSD validating parser, which I
suspect wouldn't be something one would use with MircoXML).

This decouples schema documents from XML documents which is a great
simplification (IMHO)

I could definitely see using MircoXML to send to say mobile devices or
simple apps which could have a much faster and smaller parser,
but still use XSD on the back end to validate them before sending.

It seems the main point of microxml is that it junks dtd because they 
are seen as too much of a complication. I can understand that pov, but 
struggle to see how anyone could think of dtd as too much of a 
complication and then consider using the untamed monster that is xsd?
