What is the correct format for named character entities? According to
the online specs, I should be able to write:

	dchar ch = '&amp;';

But gdc-4.6.2 refuses to compile this; apparently it wants:

	dchar ch = '\&amp;';

Which is right??

The latter is right. The spec must be implying the \ character as all of the other special character syntaxes use it. One of the reasons is that character are specified the same way in strings. So "&amp;" is 5 characters as written. Again, a \ character is required to distinguish it as a single character literal. Ali

[...] Hmm, then the specs need to be fixed, since currently it says: EscapeSequence: \' \" \? \\ [...snip...] NamedCharacterEntity And: NamedCharacterEntity: & Identifier ; Somewhere in there a \ needs to be included.
