I as well had an action on whitespace handling, namely regarding 
what the spec says [1] - here is what I found:
 
Section 4.7 'White Space handling in attribute values' 
of the XHTML spec [2] tells us:
 
=============================================================
When user agents process attributes, they do so according to 
Section 3.3.3 of XML [3]:
 
 + Strip leading and trailing white space. 

 + Map sequences of one or more white space characters 
  (including line breaks) to a single inter-word space. 
=============================================================
 
Further, Section 3.3.3 of XML [3] defines in detail the 
'Attribute-Value Normalization', such as EOL handling, 
mapping of (#x20, #xD, #xA, #x9) whitespace to a single
#x20, and CDATA/NMTOKENS declarations.
 
Given the above, and when I understand Ben right, my 
conclusion would be that none of the browsers actually
behaves correctly.
 
Did I miss anything?
 
Cheers,
     Michael

Subject: action on white-space preservation in attributes





Hi all,

I had an action to check on white-space preservation in browsers. It
appears that Safari3, Firefox2, and IE6/7 all preserve white space in
any position of attribute content.
