This DTD fragment defines the full ICADD Braille table model
altered to be, as far as possible, backward compatible
with the recent drafts of the late/former HTMLplus.
It is intended to be a superset of html-t1.dtd. The major
differences are in formatting: This DTD defines formatting
attributes to carry values that might otherwise have to be
calculated or established arbitrarily by a Web browser.

<!-- TABLE is the top-level table element. CAPTION replaces H3, the
Braille heading level for a table title and is allowed either before
or after the table (or both). -->
<!ELEMENT TABLE - - (CAPTION?, NOTE?, TGROUP, CAPTION?)
-- CAPTION is allowed before or after table structures;
model is simplified to suggest both could be used. This
could be rewritten as an OR group. NOTE is where Braille
transcribers put contents of very long cells (kind of
reverse footnotes to avoid very wide cells) with
pointers to the actual cells. -->

They cover the entire table unless values are assigned
on the TGROUP, THEAD, TBODY and TFOOT elements.
The TGROUP model allows TFOOT either before or after
the TBODY for multi-screen or multi-page tables whose footers need
to be available for the first portion during formatting. -- >

required lower-level elements. -- >

<!-- Table Row Definitions: -->
<!ELEMENT HDROW - O (TH+) >
<!ELEMENT TR O O (TH?, THSUB*, TD+)
-- Use of TH and THSUB in TR has two major goals: Most
importantly, it facilitates the ability of braille and
computer voice software to determine the heads which
affect any individual cell in order to manipulate the
order in which they appear. Secondarily, they allow
for the possibility that the stub cells of a very wide
table may be fixed in position as a user scrolls to the right
or may be repeated on several pages in printing.
Using either TH and THSUB as the first cell in
a table row supports differentiation between, for example,
items and totals.
The model also allows sub-stub to be repeated in several
columns.
AXISNAME attribute appears on any stub-type cell, covering
the voice requirement for alternative text to be provided
if the cell content is too long to appear in the
voiced stub. It holds description for text-only displays.

are populated from databases, AXISNAME is the key to
the source of the row or column of data. In header
cells with succinct content, "axisname" may simply
be the content of the cell. Otherwise, a shortened
version. --
