Hi all,

just an attempt to clarify:

The XML Schema <sequence> *only* defines the order of the elements in the XML 
file. It *does not* impose any implicit processing order. A protocol can define 
any processing order it likes.

Also, there is one <add> and/or <rem> element at most in a request. However, 
within each of them, multiple elements may occur to represent multiple DS 
records (or keys, if you will).

Personally, I really don't care about the order in the XML document, but I 
prefer the perform the removals first and then the additions. Ulrich's way to 
reject a request if a DS record appears both in <add> and <rem> would be also 
acceptable to me, but it makes the implementation a little bit more complex if 
the <keyTag> in the <rem> section is retained -- in this case, the DS data has 
to be checked against these <keyTag> elements as well.

Regards,
Klaus
