If a browser understands the base tag but not an attribute, the entire
tag should not be ignored. This probably isn't terribly well defined;
browsers should really support a strict subset of HTML and all tags
defined therein, but the malleability of the spec and the way it has
evolved makes that difficult. Imagine if browsers that don't support <P
ALIGN="CENTER"> ignored the paragraph tag altogether.
