Re: [jats-list] 'xlink' namespace prefix definition in JATS

[Tommie Usdin <btusdin@xxxxxxxxxxxxxxxx>]

This is intentional. It was a compromise based on the recognition that Xlink
is rarely used but there are:

1. existing documents with the namespace declared that should not be
unnecessarily orphaned by a non-backwards compatible change, and

2. a few applications that do use XLINK and want/need the namespace
declaration.

(Off topic, but I can't resist: I was both surprised and disappointed in the
popular failure of Xlink. I still think it includes some concepts that we as a
community would benefit from significantly. I think the failure was/is caused
by failure to communicate and an overly-complex specification.)
