B.1 Notes on invalid documents

This specification does not define how conforming user agents handle 
general error conditions, including how user agents behave when they 
encounter elements, attributes, attribute values, or entities not 
specified in this document.

However, to facilitate experimentation and interoperability between 
implementations of various versions of HTML, we recommend the following 

   * If a user agent encounters an element it does not recognize, it
     should try to render the element's content.
   * If a user agent encounters an attribute it does not recognize, it
     should ignore the entire attribute specification (i.e., the
     attribute and its value).
   * If a user agent encounters an attribute value it doesn't recognize,
     it should use the default attribute value.
   * If it encounters an undeclared entity, the entity should be treated
     as character data.

Yes, it is a SHOULD, not a MUST.
