Hello,
There was a bug where liblouisutdml was inserting additional text other
than the actual translation into a brl node.
Brandon noticed a particular mtr element which was causing this. It
turns out that the problem with that mtr element was that it only
contained one mtd element where as others had two mtd elements.
According to the MathML specification this is perfectly legal and what
the software should do is infer empty mtd elements to the right of the
explicitly given mtd element on that row, so that the explicit and
inferred mtd elements equals the number of columns in the table.
It appears LibLouisUTDML is not obeying this part of the specification.
My main question is how we want to go about solving this, should it be
fixed in LibLouisUTDML or should applications correct this in the XML
they give to LibLouisUTDML?
I would say that it would be more correct that LibLouisUTDML deals with
this. However it probably is simpler todeal with in other applications
with higher level languages like Java.
Also there is a second question relating to this, how should
LibLouisUTDML deal with mtd elements with rowspan and columnspan
attributes which are greater than 1? Is there currently any feature of
LibLouisUTDML which can deal with rowspan or columnspan?
It probably is worth trying to fix rowspan and columnspan at the same
time as fixing inferring mtd elements, unless its deemed that rowspan
and columnspan are lower priority.
