Tra l'altro:

* The return of the outline feature. The feature, allowing users of  the validator to check if the headings of their document provide a  reasonable outline, was broken in version 0.7.3 and at risk for the  next versions. It is now fixed, and secured for future versions. The  W3C Semantic Data Extractor[1] is also recommended for that purpose,  and more.[1] http://www.w3.org/2003/12/semantic-extractor.html
