That would say under XML Schema, a document can 
be rootless in the classical sense.  It is more 
like VRML, which having been designed from the 
beginning to be object-oriented, has no document 
root, simply a comment that must be included 
at the head of the file.  XML Schema in that 
sense has been oriented toward object design. 

Is this the case, that by having multiple 
global elements, we can design a schema 
with multiple document roots, or perhaps 
simply, multiple trees?

Yes, all you have to do is to define these 4 elements as global.
