+TODO list for vorbis spec docbook conversion.
+
+* Get the figures working in pdf. Jade seems to be doing something
+  (suboptimal) with <graphic>, and nothing at all with <imageobject>.
+
+* Proof against html original and remove it.
+
+* Reset all those nested lists of decoding structions in docbook. They
+  don't wrap properly in the printed version, and they don't look so
+  good. Easy but tedious.
+
+* Set remaining auxiliary material.
+
+* Get vector versions of the figures from Monty and/or create them anew.
+  We need eps versions for the printable version. Optionally, have the
+  makefile run them through ghostscript to create the pngs for the html
+  version if the docbook processor isn't smart enough to do so.
+
+* Get the equations working. We should have one version, either latex or
+  mathml from which both the html and print versions are generated. Latex
+  source is in the alt tags in the document.
+
+* Normalize variable naming. The current spec uses brackets to indicated
+  values decoded from the bitstream. In html and pdf we can use tt font
+  to indicate this, so the [] is redundant. Remove them from scalars and
+  either keep them for vectors, or set the vectors bold tt. Note that
+  this requires resetting the already tt sections.
