Actually this isn't quite right. There's a typo (it should be )
but there's also a less obvious error.
The declaration above will define amp to contain the single character
"&", since character entities in entity definitions are expanded.
When the entity is used, it will be re-expanded, producing a syntax
error, since the parser encounters a bare ampersand. The solution is
to use a "double-escape" in the definition, like this:
<!ENTITY amp "&#x0026;">
<!ENTITY amp "&#38;">
which is the "canonical" definition given in the XML spec.
The effect of this is that amp is defined as "&" and this is
expanded to produce "&" when the amp is referenced in the document.
