More specifically, any series of white space between the first 
non-whitespace character and the last non-whitespace character are 
supposed to become a single space when parsed (according to XML rules 
and probably SGML as well).  However, as Bjoern said, any whitespace is 
invalid in a URL so your HTML is not invalid, your URL is invalid.  If 
there needs to be whitespace somewhere, put it at the beginning or end 
of the attribute because is is supposed to be stripped when parsed and 
will make no difference if parsed properly.
