SGML Declarations for SHML
SHML 1.0 DTD Drivers | DTD Modules | ISO Character Entity Sets | Revisions | Feedback
Project Mehitabel is a next-generation, modular HTML DTD (labelled "SHML 1.0") based on HTML 3.2, but with changes/improvements as described below. Mehitabel may serve many needs: authoring, document design, validation, etc. It is not meant to capture the complete array of current Web features, rather it is meant as a good, structured DTD for document authoring, with extensibility to allow for additional features. It would also be a suitable place to scrounge for HTML-based XML components, with necessary modifications. SHML is currently the basis for HTML inclusions in various prototype document types.

Please note that the revision number found in the SCCS header at the beginning of the DTD driver may be used as a reference, such as:

"-//Sun Microsystems//DTD HTML 3.2-Based Variant SHML 1.0 Draft//EN"
"-//Sun Microsystems//DTD HTML 3.2-Based Variant SHML 1.0 Santa Cruz//EN"
This DTD relaxes the restrictions on heading level hierarchies and makes optional various element end tags.
"-//Sun Microsystems//DTD SHML 1.0 Lagunitas//EN"
This DTD no longer requires heading level hierarchy, end tags on various elements, plus includes all deprecated elements and attributes.
NOTE: Current discussion with WAI (Web Access Initiative) members is leaning toward abandonment of ICADD DTD processing in preference for tools that process HTML directly. This file is included for historical purposes only.

You can view the structure of the Mehitabel DTD thanks to the perl programs dtd2html and dtddiff, part of Earl Hood's perlSGML package. A HTML 3.2 to SHML 1.0 differences file is also available, but unfortunately the dtddiff program is unable to discern content models that differ only in element ordering, so the differences appear greater than actuality. Note also that many of the changes appear due to adding ID, CLASS and internationalization attributes on many elements. If I get a chance, I'll try editing a better copy that delineates these changes.
Both the DTD and this page are a work in progress. Please report any bugs, omissions, suggestions, etc. to <email@example.com>.
