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
behavior:
* 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.
