#365 slides: RELAX-NG schema header points to DTD

[Jesse Glick]

http://docbook.sourceforge.net/release/slides/3.1.0/schema/relaxng/slides.rng

See the docs in the file header:

---%<---
Please use the following formal public identifier to
identify it:

"-//Norman Walsh//DTD Slides V3.1.0//EN"

For example, if you are using the Slides DTD directly,
use the FPI in the DOCTYPE declaration:

<!DOCTYPE slides PUBLIC "-//Norman Walsh//DTD Slides
V3.1.0//EN"
"http://docbook.sourceforge.net/release/slides/3.1.0/schema/dtd/slides.dtd"
[...]>

Or, if you have a higher-level driver file that
customizes Slides, use the FPI in the parameter entity
declaration:

<!ENTITY % SlidesDTD PUBLIC "-//Norman Walsh//DTD
Slides V3.1.0//EN"
"http://docbook.sourceforge.net/release/slides/3.1.0/schema/dtd/slides.dtd">%SlidesDTD;
---%<---

Clearly this should be referring to the .rng file, not
the .dtd file.

Still broken. Also note that in the DTD schemas, the version
numbers still say 3.1.0, even for the 3.2.0 snapshot.

Yes. But as long as the RNG is mechanically generated from
the DTD, this isn't going to be easy to fix. Eventually the
RNG file will be primary.
