Not necessarily. Perhaps that is easier to see with a pair of rules:

Must-understand: unrecognised markup from a particular namespace is
Must ignore: unrecognised markup from other namespaces must be

Also, 'ignored' should be clarified tomeen that the outermost unknown
element (including its start tag, and (if not empty) its content,
children,and end tag, are placed in the DOM but are not interpreted.

As opposed to some 'strip off the tags and process the content as
text' or 'skip ahead in parsing' type of 'ignore'.
