README creation improvements ala TEI ticket 2070

[sydb]

Per TEI #2070 step 1:

• Do not create links for <gi> or <name type="class"> if version number < 1.0
• Presume class names are encoded with <name type="class"> (not <ident>)
• Generate correct link for those (few) version numbers that are only major.minor, not major.minor.patch (by appending ".0")

WARNING
This PR cannot be considered in isolation, it must be combined with the corresponding PR in the TEI repo.

I will look at this before the next release!

Okay--it looks like we need to merge in the PR on the Guidelines repo first--to make the revised Readme XML files available for the revised processing here on Stylesheets. Is that the idea, @sydb ?

[sydb]

I have not thought about it. I do not think it matters which is first, at least not measured in minutes, beyond a possible temporary build failure. But they should both be merged the same day, or both should be rejected. It would probably be annoyingly problematic on release day if one had been merged and the other had not.

I merged the latest from Stylesheets dev branch into this branch (sydb_TEI_2070) and at the same time the latest from TEI dev branch into TEI sydb_2070. Both Test/ and Test2/ passed, and the Guidelines built without error or failure.
