to get this started, I like to see the method

string GetRemoteServiceRecordAsXML(string address, uint32 handle)

from the org.bluez.Adapter interface gets implemented and make it using
the simple service-record.dtd I put into the CVS.

I choose to simplify the DTD a lot. After having a discussion about XML
and binary representation from the SDP part of the specification, I am
pretty certain, that we should support both. The binary representation
will cover all tasks ever possible with SDP and it is the default. For
convenience we will additionally support XML as record description, but
it will only cover up to 90% of all cases, but it will be simpler to use
and easier to understand and that should be fine.

This means that all length fields are not represented in XML. They will
be chosen automatically as needed. The same applies to the UUID. So it
leaves only int* and uint* where the actual size will be taken care of
as part of the type name.

Regards

Marcel
