I just came across the URL <http://xxx.lanl.gov/hypertex/> (this is an
offical archive for storing preprints), which discusses TeX/LaTeX macros
which enables one to embed hyperlinks in the source. The idea is that a
smart browser can convert those to real hyperlinks.
Are there any plans including such macros in LaTeX3? (If not, it seems to
be a good idea.)
