Hi Stefan,
Re:

Good point.

Yes, jEdit does this, but I can't see myself getting the time to (a) learn
Lisp and (b) implement something similar for Emacs nXML, so I'm going to
drop this idea for now.
Thanks for the patch anyway, that's very kind of you.

Yes, I can help, but be prepared for some tedious detail. If you're prone
to responding "tl;dr", look away now ;-).
From the description of the html5-schema package (
https://elpa.gnu.org/packages/html5-schema.html):
> The RelaxNG files are taken straight from
https://github.com/validator/validator.git's via:
> git subtree -P schema/html5 split
The problem with that approach - taking files "straight" from the v.Nu
GitHub repo - is this:
> Some schemas in the v.Nu GitHub repository - in particular, schemas that
combine markup languages - refer to file paths that do not exist in the
repository. The paths exist only in the context of the distributed files
(inside vnu.jar).
> These nonexistent paths prevent the schemas being usable directly from
the v.Nu repo (for example, via GitHub Pages URLs).
For details, see the readme at (my) repo:
https://github.com/unsoup/validator
As described in that readme, I extracted the schemas from vnu.jar and
compared them with the schemas in the repo.
Today, prompted by your email, I went two steps further:
1. I developed a Microsoft Windows PowerShell script (sorry, that's my
primary working environment) that completely automates a process that I
had previously done manually:
a. Downloads the latest release of the vnu.jar .zip from GitHub
b. Extracts vnu.jar from the .zip
c. Copies the schema files from their single ("flat") directory in vnu.jar
to a directory of your choice, re-creating the same relative directory
structure as the URI paths used by v.Nu.
The result is a set of schema files that matches what v.Nu uses, with
relative include paths that work.
2. I uploaded the results of running that script to:
https://github.com/unsoup/validator/tree/gh-pages/schema-release
To improve the html5-schema package, replace its contents with the
contents of the unsoup/validator/schema-release directory (perhaps minus
the readme).
That is: use the v.Nu schemas from vnu.jar, not from the GitHub repo.
To "accept" SVG elements in an XHTML5 document, use the following schema
file:
xhtml5_rdfalite.rnc
which matches the Validator.nu "preset":
XHTML + SVG 1.1 + MathML 3.0 + RDFa Lite 1.1
For details, see the readme at:
https://github.com/unsoup/validator/tree/gh-pages/schema-release
(I might add to that readme a table that matches Validator.nu presets to
schema file names.)
Let me know how you get on.
I plan to upload that PowerShell script in the next few days.
In time, I might even schedule that script to run every so often, and
introduce further automated steps, to get the latest-release vnu.jar,
extract its schemas, and commit any changes to the copy in the
unsoup/validator/schema-release directory.
Cheers,
Graham
