Are line breaks in XML attribute values allowed?

Question

I realise that it\'s not elegant or desired, but is it allowed (in well-formed XML) for an attribute value in an XML element to span multiple lines?

e.g.

<

Seems to say everything except <, &, and your delimiter (' or ") are OK. So newline should be, too.
