tables and latest ODF spec

In the v7-02 ODF spec at http://www.oasis-open.org/committees/download.php/28121/OpenDocument-v1.2-v7-02.odt
I found the following items of interest to our group: 

18.921 table:is-sub-table (Note the
last sentence from the editor.)

If a table cell only contains a single
table but no paragraphs or other content, this table can be specified as
subtable. It then occupies the whole cell and no other content can appear
in this cell.

The borders of a subtable merge with
the borders of the cell that it resides in. A subtable does not have its
own style. A subtable is essentially a container for some additional table
rows that integrate seamlessly with the parent table.

A nested table is turned into a subtable
with the attribute table:is-sub-table that is attached to the table element.
A nested table that is not a specified to be a subtable appears as a table
within a table, that is, it has borders distinct from those of the parent
cell and respects the padding of the parent cell.

Ed. Note: The examples have
been removed, since they implied that is-sub-table is appropriate for simulating
row- and colspan.

Appendix E.3 Tables in Presentations

Users importing non-OpenDocument slides
that contain tables need access to the table structure via their assistive
technology. Therefore tables imported into an OpenDocument application
from another file format must have their structure preserved, and when
saved as OpenDocument should be saved as as embedded spreadsheets.

Is  there anything else I should
look for?

p.s. The link to our guidelines is bad
here:
