It is useful to know if a semi-colon has accidentally been omitted from an
entity reference, or if you've unintentionally used a sequence that looks like
an entity reference.  This could be defined so that it is valid when:

1. The value is alphanumeric ASCII followed an equals sign
2. The value does not match one of the defined entity references.

So the most common cases of "?x&foo=1" would be valid.
But "?x&copy=1" would be invalid because &copy; is an entity and, in this case,
would be resolved to "?x©=1", which is not likely what the author wants.
