The answer is no, according to the CALS table spec at
http://www.oasis-open.org/specs/a502.htm

"Within an <entrytbl>, inheritance for an <entry> is from <entrytbl> (or its
<thead> if the <entry> is also in it) instead of <tgroup>, and cannot be
from <thead> or <tfoot> of that <tgroup>."

However, I'm not sure the XSL stylesheet is behaving correctly in an
entrytbl.  It uses an ancestor::tgroup in computing the inherited attribute
value, and an entrytbl does not have a tgroup.  I'm going to go through that
template again with your example.  The entrytbl does seem to inherit the
colsep="0" from the outer tgroup, and that is not correct.

Yes, it should align right.  The 3rd colspec applies to entry elements in
that column even if it is not referred to by name.
