I need an example of this blobby array
scheme. To me this concept makes no sense. We're embedded in XSD's type
system, so if you can talk about arrays at all, then there has to be a
logical model for them, and that means a way to talk about them in XSD
independent of DFDL annotations.
We COULD propose an extension to XSD
for arrays. Is that what you mean?

I definitely want to see data virtualization services based on DFDL, but
I
don't think we need do anything specific in the language to provide
externally available access methods for parts of the described data set.
