WFS Inline Schema

What do you mean by inline schema? Do you mean defining the XML Schema
in the XML instance document (i.e. the GetFeature response) itself? If
yes, that's not going to happen. xsi:schemaLocation provides a
namespace and URL value for an XML parser to seek the XML Schema
document and validate against it.
Perhaps I don't understand your problem clearly enough. Do you have
full examples of both the XML instance document, as well as the schema
it uses?
