     1.7 +<p>The CSS Working Group strongly recommends that document languages do
     1.8 +not allow multiple style attributes on a single element. If a document
     1.9 +language allows multiple style attributes, each is parsed independently
    1.10 +and treated as a separate style rule, the ordering of which should be
    1.11 +defined by the document language, else is undefined.
