[doap-interest] doap:revision, sorting and version number notations

According to "Describe open source projects with XML part III"
(<http://www-106.ibm.com/developerworks/xml/library/x-osproj3/>),
doap:version's have to be current versions (with, if necessary, different
branches): "Although [...] the tracking of each project release is not part
of the first phase of DOAP, you still a need to describe current releases of
software projects".

To solve this problem, it could be an idea to create new elements /
attributes: doap:versionNumberMajor, doap:version#Minor, etc... But that
would be really... heavy.

Furthermore, a parser could explode such a version number (1.15.1) using the
dots, and think according to it: if the leftmost number of the version a is
greater than the leftmost number of the version b, then... etc.

Another problem will be with alphas, betas and release candidates (a, b,
rc)... Still the problem of standardization.
