SVG Implementation Resources, Guidelines

Hello everyone,

I'm not sure if I'm in the right place to ask this, so please inform me if
you know where I should turn to.

We're looking to implement support for SVG 1.1 (2nd edition) in our
application, but we've had difficulties finding information on the approach
others have taken when turning the spec laid out in the html file into an
implementation in any given programming language.

Are people simply manually referencing the HTML, or is there a more
machine-parsable format of the standard available? Are people parsing the
HTML directly?

I was thinking the doctype definition would be a good document to parse,
but the versions available on the W3C website appear to be limited in
scope, not listing all aspects of the standard.

I did find this extensive DTD for SVG 1.1 in a github repo which looks to
list all elements, attributes, etc., but I'm not sure how reliable it is,
given how the repo is unrelated to W3C. It is also not for the 2nd edition
of the standard. Here's the dtd:
https://github.com/vvvv/SVG/blob/master/Source/Resources/svg11.dtd

Again, sorry if I'm posting this in the wrong place. I haven't been able to
find a good single source of information or guidance on how to implement
SVG.

Thanks,

Valdimar
