Hi Robert,
Well, if that is the right way to use MathML with DITA, then shouldn’t we remove the MathML markup from DITA (effectively removing inline MathML support). And
provide only <mathmlref>.

Hi Tarun,
That is intentional. The problem with adding those entities in a DTD is that they cannot be confined to the MathML markup. So, if we include them in the Math markup, which is included in DITA, all of those entities become available in any DITA topic, anywhere.
A lot of my customers noticed that when we tried an early beta of the math markup, and it didn't go over well (particularly among those who didn't actually use the Math markup).
The best way to get around this is probably to store your MathML documents independently of the DITA markup, and reference them with the <mathmlref> element. For example, the DITA markup could be this:
<fig>
<title>My equation will appear here</title>
<mathml><mathmlref href="">
</fig>
When the math file is stored externally, it can (and should) use the original MathML DTD, which includes the full range of entities. Processors should import this math content and treat it as they would any math markup directly within the topic. Entities will
be understood based on the definitions in the original DTD.

I was looking at the MathML DTD fileset in the DITA 1.3 DTDs. In the file "mathml3-ditadriver.dtd", the following setting excludes the MathML entities:
<!-- DITA-specific: Don't allow use of general text entities. DITA documents should not
have any general text entity references.
-->
<!ENTITY % mathml-charent.module "IGNORE" >
From the comment along with it, this seems to be intentional. But then how will MathML actually work with DITA 1.3, if these entities cannot be included in the DITA files ?
