The & is not viewed as a terminator but as a character which starts
an entity reference. This has nothing to do with attribute delimiters.

Always quoting attribute values is good practice, especially with
respect to validation. See The Saga of the Slashed Validators,

But that's a different story.

No, that has nothing to do with the issue. If there were an entity
for the percent sign (in which case it would undoubtedly be &percnt;
to correspond to the name mentioned in an informative appendix to the
SGML standard), an attribute value containing it would still need to
be in quotes.
