Clarify that the scheme attribute does not have a default vocabulary.

[mattgarrish]

It's the only attribute that requires a prefix for its values.

Indeed... I was surprised when I saw that in the PR on processing property, I didn't remember that particularity...

See github issue epub-specs#2382.

Dave Cramer: there are a couple issues associated with this (#2378, #2382).
… this is very technical, I wish mgarrish were here to explain.
… doesn't really seems to change how the spec works, more an editorial change.
… seems like they were just looking for WG approval before merging, even though most of us probably won't have strong opinions on this.
… i'm generally in favor of explaining things in an algorithmic fashion rather than hard to understand paragraphs.
… maybe we just say that we don't have objection to merging this pending github reviews?.
