Best Approach for MathML and Equation Domain Support in OT

[super-structure]

I've done work on a plugin for math content (equation domain and MathML) for both FO and HTML5 outputs for the open toolkit. As it stands, this solves a lot of the problems for my employer but is maybe too specific in some ways for a general solution. Namely:

• this has specific formatting for a <dl> within an <equation-figure> that is not per the DITA spec
• this uses Node.js as a pre-requisite to convert MathML to SVG as an option for dealing with MathML

So, if this work were to be presented as a resolution to issue #1774, I am hoping to get some input as to which of the following approaches would be the best practice:

1. 'extract' the equation domain and mathml handling and create a PR for the OT with those integrated similar to other domains
2. submit a the plugin as a standalone inclusion in the DITA OT (a plugin version which removes those items bulleted above)
3. just leave the plugin "as-is" and rely on DITA OT users to find it via the plugin registry

My inclination is that option 1 would be the best way, as it seems to this handles the equation domain and mathml in the most consistent manner with the rest of the DITA v1.3 specification. Does anyone else have strong opinions or thoughts on this?

@jelovirt Wondering if you might be willing to weigh in on this. In the interest of resolving issue 1774, do you have a preference?
