David, Magnus,
Yes, this is somewhat Oracle-specific (more accurately it is
JDK-specific, which is why this is a proposed to be a JDK build-time
taglet, and not a standard tag in the standard doclet), but it is no
worse than the explicit Oracle-specific URLs that have been used up to
now, or the relative links using {@docRoot}/../stuff which assume that
"stuff " is available nearby somehow. I would also go further and say
this is better that the existing methodology because it abstracts all
the linking to a single taglet, removing it from inline in the doc
comments. Yes, the currently proposed taglet may assume the existence
of single "base URL", but anyone with an alternate implementation of
OpenJDK could change the impl of the taglet to use any other mechanism
to establish the link. Doing a "strings in switch" on the identifier to
select a URL comes to mind, and avoids anyone having to edit the main
source doc comments.
