The 'src' attribute purports no magic beyond the standard URI mechanism.

The implements-prefix="foo" points to a specific *namespace* URI
for the function "library". A human-assisted process to download
the right bits would only need this NS Uri as a key into whatever
information you'd want to stage, but I don't envision the
XSLT processor firing up modal dialogs or web browsers in the
middle of stylesheet execution to allow the user to "Please pick
which implementation of this function you'd like to use..."
before continuing along its merry way with the current transformation.
