because the XML parser will expand entity references when it parses the document, if it sees & it can expand it to &, but if it sees a standalone &, it doesn't know what to do with it, or if it happens to be next to another character, it iwll try to interpret that as an entity reference. There are five built-in entity references, and you can define your own as well, but custom ones you can define the values for in your DTD.
One technique is to enclose markup you don't want parse to allow these characters in a CDATA section, so perhaps: <root> <element><![CDATA[ &<myest]]></element> </root> This tells the XML parser to not parse what is contained in between [ and ]. This technique is often used in applications where javascript is used, to avoid parsing errors with Javascript operators like &. Or you can just use the character entity.

Is it simply because '&' is flagged in the parser as reserved for entities of the form "&xxx;", or is there another reason? That's all I was asking.
