Well, i don’t _think_ so, or, i don’t mean it that way.

That's one way to look at PDF - or PostScript for that matter - it's a
program that, when executed, produces (one expects) marks on a page.
Although i once wrote an interactive game in PostScript.

Tim Berners-Lee in his Design Documents wrote that an SVG document is a
function that, when executed, produces a drawing. However, this doesn't
seem to allow for other ways of using the XML that's the SVG document:
i can write an XSLT stylesheet that changes it into a SQL statement
that queries a database for circles of the same size. Our XML Promise,
as i call it, is that any XML processor is licensed to process any XML
document in any way. Similarly, it's OK to read a PDF document without
executing it as PostScript.

The rebranding part is that XML isn't central to this story, but is
instead a central _part_ of it.
