"CSS is now a programming language. XML is now a programming language." Seconded. Could we please stop call CSS a language. If not, add PDF to the list.

  > Could we please stop call CSS a language If you're going to be pedantic, be pedantic right. CSS is indeed a language, even if it's arguably[1] not a programming one.

  Interestingly, PDFs actually do contain an embedded programming language in them, a subset of PostScript. [1] PostScript, meanwhile, is actually Turing complete with conditionals and loop structures inside of it. [2] I'd argue that makes PDFs a whole lot more programming language-y than CSS or XML.

    "PDFscript" (as I like to call it) is not Turing complete. It's more similar to SVG in terms of capability. From the PDF spec: "To simplify the processing of content streams, PDF does not include common programming language features such as procedures, variable, and control constructs."
