The second one is broken; the first one works quite fine.

Further investigation after I had already sent two patches showed my 
changes to the tokenizer broke the the detection of numbers 
(floating-point). I reverted the change to 'num' in tokenizer.flex and, 
though flex complains 'integer' will never be matched, things work 
again.

The odd thing is that I copied that from CSS3's specification. Of 
course, it could also be the fact that I had a grand-total of 1h worth 
of experience with flex...

XHTML 1.0 and 1.1.

From the XHTML 1.1 specification 
(http://www.w3.org/TR/xhtml11/changes.html#a_changes):
"1. On every element, the lang attribute has been removed in favor of 
the xml:lang attribute (as defined in [XHTMLMOD])."

From the XHTML 1.0 specification, section "C.7. The lang and xml:lang 
Attributes" (http://www.w3.org/TR/xhtml1/#C_7):
"Use both the lang and xml:lang attributes when specifying the language 
of an element. The value of the xml:lang attribute takes precedence."

Yes, it looks like it's a prefixed element. But it's the only element 
that is so.

The problem is that XHTML 1.1 removed "lang", so in order to write XHTML 
1.1-compliant pages, I had to use "xml:lang". And, of course, since my 
point was supporting the :lang() pseudo-class selector in the pages I'm 
writing, I had to add that attribute as well -- though changing the 
DOM::HTMLElement was probably not a good idea as it breaks compliance 
with DOM HTML specs.
(it's been only 4h that I found out those specs)

By the way, Quanta supports it in the Attribute Editor.
