Hmmm... throwing petrol onto the fire here, how do you guys feel about XML
schemas that feature non-XML sublanguages like XPath or the path thingies
in SVG? Your argument can be applied to those, too; companies could add
proprietary extensions to XPath that aren't self describing (XPath is
hardly self describing as it is once you get beyond
/element/element/element :-)

I'll make my point again:

*It's a myth that binary formats are somehow harder to read than
text-based formats.*

Binary formats that are well specified and take off end up with commonly,
freely, avaialable tools to view them. Consider JPEG files, GIF files, PNG
files, zip files, and even filesystems (ISO9660, FAT, ext2fs, FFS, ...).

TCP/IP. Consider that, too, as a good case in point. Do you see any
proprietary TCP/IP variants out there?
