Commenting a DTD

[bluephoenix]

I would like to be able to comment my DTD's similar to the way the W3C does their DTDs, as in this example:
<!ENTITY % head.misc "SCRIPT|STYLE|META|LINK|OBJECT" -- repeatable head elements -->

However, inserting comments within a declaration errors out on me; instead I have to write:
<!-- repeatable head elements -->
<!ENTITY % head.misc "SCRIPT|STYLE|META|LINK|OBJECT" >

How can they "get away with it" and not me? Is there something I'm not doing correctly?

Thanks,

Hm. I'm not sure if their definition is correct. Might want to ask them about that on their mailing list.
