It is a good idea for specs to have a preferred prefix. That is because
a name in markup is a name, and a good name is readable.   A string with
"xsl" is a good prefix for an XSL element, for example.

An XML DTD is a limited, fully-resolved structural schema for that
instance. It gives one lexical form for a document that uses elements
from a set of namespaces. In a sense, a DTD is not a schema at all, in
the way some people think of schemas: it is a way of removing constants
to headers and signifying how to interpret certain attribute values as
the ends of links (rather than being a way to constrain relationships
between arbitrary information items, or being a way to map between
storage/access technology and the DOM, or of providing datatyping).
