Hi Jim I can answer your first question. I'll have to leave someone else to answer your second.
Your schema defines a targetNamespace of "http://www.aptas.com/ontology";. datafeed is defined as a top-level (i.e. global) element. This means that instance documents need to refer to that element using a qualified approach i.e. using both the namespace and the local name of datafeed. However you have also defined elementFormDefault="unqualified". This means that all local elements _must_ be referred to in an unqualified way i.e. without a namespace (you can override this default on individual elements with form="qualified|unqualified", but that's not relevant to your problem below). Defining xmlns="http://www.aptas.com/ontology"; does the right thing to the datafeed element (qualifies it with that namespace) but unfortunately it does the same thing to all child elements as well which is incorrect. You can either do as you suggested and in the instance document define xmlns:xxx="http://www.aptas.com/ontology"; and then use xxx as a prefix _only_ on your global elements. Or you can change your schema such that elementFormDefault="qualified". Then validation will expect both global and local elements to be namespace-qualified and you can use the instance document you have below.
