I know the main reason for this is because XML and HTML5 have different way of defining what is a whitespace (e.g. form-feed is a whitespace in HTML5 not in XML), and HTML5 has many way to set an element with whitespace properties (e.g. with CSS). But in practice a filter will very likely have to extract pre and textarea as if they had xml:space='preserve'. Moreover, once extracted the content is likely not in an HTML5 document anymore, but in another format, likely XML (e.g. XLIFF, TMX) where the specifics of HTML5 whitepace will go to the drain.

Hmm. Wouldn't it be cleaner to rephrase
"The Preserve Space data category does not apply to HTML documents in 
HTML syntax."
? I don't know how, but we want the HTML5 defaults to be normative, 
right? That means: the data category applies to HTML5, no?

Agree in terms of testing and normative language - sorry for being 
unclear: do we want to give any recommendations wrt to people processing 
HTML that is "before" HTML5? After all, of an ITS processor encounters 
the "title" attribute at a "p" element" in the HTML namespace, the 
processor may not know whether the "p" element comes from an HTML5 
document or from XHTML. And people may want to have processing chains like
1) create content in a CMS in HTML4
2) convert that to HTML5
3) process it in a localization workflow
I think this is what Linguaserve did actually. Having some advice here 
about what default processing to expect in 3) might be useful also for 
content creators working with 1) - no?

Best,

Felix
