Flashes CrossDomain DTD

Why is it that the DTD for the cross-domain policy file doesn’t contain a definition for the ‘to-ports’ attribute when it is clearly recommended in the Flex 2 docs??

Surly it is not too hard to add to add one little snippet to the DTD??

Doesn’t take much, and then my nice IDE (that understands such things as DTDs) would not constantly warn me that the attribute is not declared.

I know, it is a small thing but it is the only warning in my entire app! It would be nice if it would just go away…
