I am going to assume that my last line is the problem here. I suppose that
last line could be read as asking for a way to remove the entire tag and not
just change the sequence information. The problem is that the .NET API for
creating web services does not seem to allow me to change that information
from the default of "sequence" to "all".

Having said that, the implementation on the PERL side does adhere to the
service standard. Hashes are just data constructs -- the output can be
massaged however we see fit. Since it’s a hash, however, it doesn't retain
information about order or structure and thus allowing the web service to use
the "all" option would make the PERL implementation faster and cleaner.

If the .NET API doesn't provide for a means of changing the value of the
sequence tag, then I would have to say that it’s the .NET implementation with
the problem adhering to standards. I doubt that, though -- I am sure there
is a way to do this, I just haven't found it.
