I assume so. It will most likely just ignore it though. If there is no Sitemaps DTD, I think it has to ignore it unless it expects it.

From Wikipedia:

In the markup languages SGML, HTML, XHTML and XML, a character entity reference is a reference to a particular kind of named entity that has been predefined or explicitly declared in a Document Type Definition (DTD). The "replacement text" of the entity consists of a single character from the Universal Character Set/Unicode. The purpose of a character entity reference is to provide a way to refer to a character that is not universally encodable.

In short, no. Not unless the preprocessor is very forgiving.
