IDL errors

The IDL in the draft doesn't compile. The following errors occur:

- No forward declarations.
- int used instead of long.
- Order of interface definitions doesn't take into account inheritance.
- All constants in Node clash with interface names. The CORBA spec
(section 3.2.3) clearly specifies identifiers are case insensitive.
- "typedef sequence <wstring> StringList;" appears nowhere but is used
in AttributeDefinition.
- In interface EntityDeclaration DocumentFragmentreplacementSubtree
- In EntityReference "void expand(in  );" occurs while it should have no

I suggest to introduce the module org::w3::dom.

The attached files compile. That's all I can say about them at the

With kind regards,
