Absolutely not. XML is a language to define a tree-like structure of elements
and attributes. SVG just defines what those elements are. When you write a SVG
you pretty much write it declarative. 
There are Turing complete languages written in XML - XLST for example, but that
doesn't mean XML is. SVG would be similar only if combined with JavaScript.

PDF compared to EPS dropped all the control structures so it pretty much was
made into a declarative format. That's why there are PDF parsers around and
it's not that hard to write one yourself. Not so for EPS - if you want to
support it you pretty much must write a complete language interpreter or it
just won't work.

If we can convert EPS in documents to PDF and use pdfium for rendering, that
would already solve the issue for us, but as I said I would drop EPS support as
an input format as we really don't have it - not even now or in the past. The
hacks like this in VCL are just slowing us down when we try to modernize it.
