Thank you, any help would be greatfully appreciated.

The current HTML standard as defined by the DTD forbids nested lists. It is
therefore no surprise that the line mode browser doesn't support them. Other
browsers have made extensions to the standard. It is certainly true, that the
SGML DTD doesn't specify how such lists should be rendered, however, the
accompanying description should provide sufficient guidelines, that authors
will have an adequate idea of how each construct will appear. The current
document says for example:
"The representation of a list is not defined here, but a bulleted list for
unordered lists and a sequence of numbered paragraphs for an ordered list
would be quite appropriate. Other possibilities for interactive displays
include embedded scrollable browse panels."
The current spec needs extension to define what kinds of nesting of list tags
are permitted together with some comments on rendering issues.

I think you are mistaken here. Forms can be defined in terms of a collection
of fields with specified types and allowed values. My proposal does indeed
do this - leaving it up to the browser to decided how to render the form. One
may also want to make it possible for authors to pass hints to browsers, but
this is a separate issue. Tables too, can be specified without getting mixed
up in the details of rendering, although some layout hints are useful.
