Well, just take SVG 1.2 and remove Animation and Script stuff,
this could and SHOULD be "generated" if the specs as some tags in it.


There might be a need for:

Tiny Static SVG [without CSS]
Static SVG [with CSS]

Also, maybe using .ssvg and .ssvgz for static scalable vector graphics.

Another proposal could be .pvg and .pvgz for printable vector graphics
or .psvg and .psvgz for printable and scalable vector graphics.



Another thing, I find strange is that:
[unless it changed from the last time I checked]

SVG Basic is not a superset of SVG Tiny.

In the sense that some stuff in Tiny are not implemented in Basic or Full,
they have a totally different approach/syntax.

As this been fixed?
