commit: 6ef11f64a2d763360542bd6a3c74da46f15dfa23 Author: Ulrich Müller <ulm <AT> gentoo <DOT> org> AuthorDate: Sun Jan 16 21:59:15 2022 +0000 Commit: Ulrich Müller <ulm <AT> gentoo <DOT> org> CommitDate: Mon Jan 24 18:16:10 2022 +0000 URL: https://gitweb.gentoo.org/proj/devmanual.git/commit/?id=6ef11f64
devbook.rnc: Change from DTD to RELAX NG compact schema The currently used DTD format has several limitations. It does not support data types, and it is not expressive enough for some element syntax used in the devmanual. For example, it cannot accurately describe the uri element which comes in two alternative forms (namely, with the link in its body text or as an attribute). RELAX NG is chosen because it has a variant with a compact and very readable non-XML syntax, and it is well supported both as an input and as an output format by conversion tools like app-text/trang. Also, we need RNC for app-emacs/nxml-gentoo-schemas anyway. devbook.rnc is the source file, but the generated devbook.rng is also committed to the repository, in order to avoid an additional dependency on trang or rnc2rng.
