UMLR — Please provide running footers or headers indicating the section/subsection of a page

The UML 2.5 document has great hyperlink/navigation support.
However, since sub-sub-sections are unnumbered, it is sometimes difficult to tell where we are in the document if the sub-section runs across multiple pages.

For example, look at sub-section 14.2.3 Semantics. The short title makes sense for the bookmarks but in the document itself, it would be easier if we had: 14.2.3 StateMachines Semantics
This particular sub-section runs over several pages and has several sub-sub-sections; e.g. "States" on p. 319. It's hard to tell we're in the middle of 14.2.3.
Unfortunately, Acrobat doesn't have a way to highlight the bookmark corresponding to the page we're currently reading.

I suggest adding a footer or header with the numbered section or sub-section title to each page.
It would be even better if the footer/header were in fact a hyperlink to jump to the beginning of that numbered section/sub-section.
