You'll have to find better prior art than those. Pei and I had a lengthy
discussion on the timing of his Viola work on the VRML list last fall. He
then admitted that he had neither published nor released a version of Viola
supporting inline apps before the Eolas demonstration at the Bay Area SIGWEB
meeting in 1993.

As for the comment concerning the Z39.50 standards committee meeting, our
claims relate specifically to embedded interactive program objects in World
Wide Web documents, not just downloading executable code for general
document rendering.
