Just to be clear. Let us assume GMF does output SVG. What you are saying
is that M2T will output both the text file and the SVG file. In other
words M2T will invoke the GMT "thing" to output the SVG file. And that
getting M2T to invoke GMT is just a download and a configuration task, and
not writing code, correct?
As a side node, SVG is just a dialect of XML for 2D graphics.
