Subject: Element Content Dependent on Attribute *Value*?


Is it possible to make element content dependent on the attribute value?

http://www.w3.org/Encryption/2001/Drafts/xmlenc-core/Overview.html#sec-Encr
yptionMethod ... The permitted child elements of the EncryptionMethod are
determined by  the specific value of the Algorithm attribute URI, and the
KeySize child  element is always permitted. For example, the RSA-OAEP
algorithm (section  5.4.2) uses the ds:DigestMethod and OAEPparams
elements. (We rely upon the  ANY schema construct because it is not
possible to specify element content  based on the value of an attribute.)
