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

Since user agents may vary in how they handle error conditions, authors and
users must not rely on specific error recovery behavior.

recommended to ignore the "charset=", but also are recommended to report to
the user about such error.
