[Haskell-cafe] [tagsoup] is it the expected behaviour ?

I don't think that is legal XML. The definitions of STag and Attribute
from http://www.w3.org/TR/xml11/#NT-STag are:
 STag ::= '<' Name (S Attribute)* S? '>'
 Attribute ::= Name Eq AttValue
And 'S' represents one or more whitespace characters, so it seems
clear that they are not allowed between Name, Eq, and AttValue.
Whether this is the right behavior for TagSoup, which is styled as a
fast-and-loose XML/HTML processor, is another matter.
If I haven't seen further, it is by standing in the footprints of giants
