The xstream.name is the name of the field not the data it contains - it is returned via the field iterator, or specified by the application to directly access the field. If the application does not know the field names it created it will be pretty useless!!

The "Get" methods you refer to retrieve the value of properties. To retrieve xstream data you open the stream (XAM_OpenXStream) and read the bytes (XStream_Read).

It is not a property, it is an xstream. There are two types of fields - properties (which are primitive data types and have corresponding "get" methods) and xstreams (which are byte streams). As an xstream is a field so it should obviously be returned by a field iterator.

You can easily get the value of the field (as I described in my previous post).

Finally, the field would be called .xstream.name by whichever application created the XSet. There is no such "mandated field" - in fact, it is an invalid field name because a "user" cannot create files in a namespace beginning with ".".

the  getFieldType for the field name xstream.name returns "application/octet-stream"

what is the relevance of having such a field property listed by the iterator and not able to get the value?
