Goodbye DTDs
So long, PSGML, hello nxml.
In the course of a full life, one must be prepared to abandon one's baggage.
Today, I take the plunge, I turn my back on DTDs.
To celebrate, I ripped all the PSGML-mode
elisp out of my .emacs file. I ripped
XSL-IDE mode out too.
I'll be using James' nxml mode from
here on out.
Next up: retooling xjparse, the command-line
script I rely on to validate XML documents, so that it does RNG validation instead.
This'll bang me right up against the “how do I know what schema to apply”
problem. But that needs thought anyway.
I won't be completely free until DocBook has moved to RELAX NG. And I'm going to be haunted by the occasional entity declaration for a while too.
But it feels good anyway.
