>A downside to PostScript is that it is a Turing-complete programming language. Defining a subset of it that gets rid of flow control would make it too verbose and harder than necessarily to write by hand ... Is there a (semi-)standard vector graphics markup format simpler than SVG that's purely declarative? I couldn't find one.
I was under the impression that PDF is a Turing-incomplete subset of PostScript in a pre-processed form. No idea how fun it would be to manually create PDFs, but apparently you can convert PostScript documents to PDFs easily by recording the drawing commands that your document produces as it renders/executes.
The section of the Fount of All Truth (Wikipedia) to you refer to doesn't seem to say that PDF is in fact Turing-complete. In fact it makes it sound like PDF is the result of running a PS document to completion and then taking a "screenshot" of the result. ("Screenshot" as in a snapshot of all the rendered primitives, curves, text, etc.)
