All suggestions are extremely welcome.
As always, a prettier HTML version of this will be posted shortly at
http://purl.oclc.org/NET/xschema.

2.6 XSchema Extensions
XSchema provides areas in which XSchema developers can provide supplemental
information and metadata regarding XSchema components in both human- and
machine-readable formats. Human-readable information is provided through the
use of a subset of HTML that conforms to XML syntax, while machine-readable
information may be provided through the XSC:More element.
2.6.1 Documentation Extensions
Human-readable documentation for XSchemas should be provided using the Itsy
Bitsy Teeny Weeny Simple Hypertext format created by John Cowan. The full DTD
is available at http://www.ccil.org/~cowan/XML/ibtwsh.dtd. Documentation that
uses portions of the IBTWSH format may be included in the XSC:Doc element, a
subelement available to all declarations. The XSC:Doc element provides basic
formatting options for XSchema documentation.
<!ENTITY % ibtwsh SYSTEM "http://www.ccil.org/~cowan/XML/ibtwsh.dtd">
%ibtwsh;
<!ELEMENT XSC:Doc %horiz.model;>
Any element allowed in the horiz.model set of elements (A, BR, SPAN, XML,
CITE, CODE, DFN, EM, KBD, SAMP, STRONG, VAR, FONT, or parsed character data)
may be used in the XSC:Doc element.
***- John - Any thoughts on namespaces for IBTWSH? Any connections to style
sheets, or should that be PIs like XML?
2.6.2 Other Extensions
The XSC:More element (coming soon to all elements that include XSC:Doc)
provides an area which developers can use to create their own supplements to
XSchema, defining content types more tightly than is possible through XSchema
1.0. The XSC: More element has a simple ANY content model, though XSchema
processors should prohibit the appearance of any elements from the XSchema
namespace in this area.
<!ELEMENT XSC:More ANY;>
