Right. Jacque mentioned above that it was originally described as a container. But even then, it's not really a normal container. 

For example, the following pairs of statement do something basically different, whereas with a normal container they do something similar.

put "x" into url <whatever>
get url <whatever>

put "x" into word 3 of url <whatever>
get url <whatever>

I usually think of things such as urls and xml as 'external resources' in the sense that they are defined outside the context of LiveCode. As such, we can't expect the normal LiveCode commands and functions to work in the same way as they would for LiveCode containers. Maybe "object marker" is a better term, but that takes us into a whole other area. :-)
