The scope attribute of a table cell can be "rowgroup", which is nicely
parallel with colgroup.

There is no such element, nor is there any easy cross-reference to
discover that rowgroup is an abstract class meaning "any of thead,
tbody (which can repeat), or tfoot"

Even when these elements are described as similar, they are often said
to delimit table sections rather than rowgroups, so a text search may
not find them.

When rowgroups are mentioned explicitly, the text says that each of
these elements "contains" rather than "creates" a rowgroup, which
again sent me looking for a rowgroup element.

Suggested changes:

At http://www.w3.org/TR/xhtml2/mod-tables.html#adef_tables_rowspan
change:
"""
rowspan = Number
This attribute specifies the number of rows spanned by the current
cell. The default value of this attribute is one ("1"). The value zero
("0") means that the cell spans all rows from the current row to the
last row of the table section ( thead, tbody, or tfoot) in which the
cell is defined.
