#537 Support for non-ISO schematron (1.4) should be removed

[Martin Holmes]

The spec for constraintSpec/@scheme includes the value "schematron" (meaning the old 1.4) and "isoschematron" (the current version we all use). Council discussions 2014-11-19 propose that we remove the former (which we no longer use and no longer want to encourage), and change the latter value to simply "schematron" (meaning ISO Schematron). This involves:

1. Changing the spec.

2. Changing usage in the Guidelines.

3. Changing the Stylesheets.

4. ???

This has to be carefully planned and run past the community, of course.

[James Cummings]

Assigning to SB to discuss with council how to implement carefully.

[Syd Bauman]

Council agrees it should be eventually deprecated and removed. Step 1, of course, is to make sure the Guidelines themselves don't use 1.x.

Step 2 is to go through and try to see that there are any consequences Martin hasn't listed (i.e., #4 in OP).

Step 3 is to run this by TEI-L and figure out how to deprecate.

[Syd Bauman]

As of revision 13281 there are 52 <constraintSpec>s in the Guidelines, of which all are isoschematron (i.e., none are schematron). So at least that part is easy :-)
