I have pushed the changes I made regarding AsSVG to my github (https://github.com/JordanChin89/Ingres).  The implementation is based off of the documentation Adriel drafted previously, which is based off of AsSVG as implemented for postgis.  However, polygons are handled the way postgis does, using 'path' elements, to support interior geometry.

Next is to write the SEP tests for the function (which will of course clear up whether the function's inputs/outputs are as desired).  Having not touched the tests in a while, the questions I can remember I have about them are:

1) What determines where a particular test goes?
2) If a new test file needs to be created, how is one written/what is generated by the sep program? (when updating the SEP tests, I used a script to modify the files directly, then ran them in sep which fixed any formatting problems I had, while confirming they still worked.)
