Actually, that's not 100% true: while & is a pre-defined entity, the
questioner expressly mentioned that he/she wanted to use a DTD. As the
second paragraph of the REC's section that you pointed to says:
All XML processors must recognize these entities whether they are
declared or not. For interoperability, valid XML documents should
declare these entities, like any others, before using them.
I believe the word "valid" there says that you can reliably use them
without declaration only in well-formed documents. If you want an
interoperable DTD, they've got to be declared.
