Template:l/version
from HTYP, the free directory anyone can edit if they can prove to me that they're not a spambot
Assuming that the first two parts of the title constitute a version-documentation path (project/version_marker), links to a subpage within that version.
The implicit understanding is that we're linking to a thing named {{{3}}} that is a {{{2}}} in version {{{1.2}}} of project {{{1.1}}}, although not all of this information is necessarily used.
