"[HTML5]space" has a very clear meaning: these are characters used for 
HTML source formatting; any sequence of "[HTML5]space" is equivalent to 
a single space. Surely "[HTML5]space" should include TAB, VT, LF, FF, 
CR, Space, NEL, LS and PS.

As for the "[HTML5]White_Space" category, its purpose is really unclear. 
The rendering of characters in this category (those that are not 
included in "[HTML5]space") should be defined in the Unicode standard, 
not in the HTML standard.
