Am I to understand from this paragraph that there would be something
wrong with uuencoded or base64'd resources, like audio clips or even a
Java class, between a start and end tag?

I thought this would be a given.  Sure using XLL or simple url hrefs are
great, but many times the requirement is for a single file with all
resources literally included.

This is similar conceptually to the intent of MIME, and MHTML, and OLE
(at one time the E meant something -- embedding). Syntactically MIME
derived methods aren't nearly as nice as stuffing the resource between a
start and end tag.

Take a look at the Internet Open Trading Protocol
http://www.otp.org:8080/  It does this all over the place.

A packaging standard to encapsulate all of the resources in the same
file is nice, but why isn't legitimate to place them all inline?

Gavin.
