Thank you all for the answers, that suggest useful tools and a very
interesting reading, I'll use these information too, but
what I am looking for is an API that allows to read a schema, to read which
elements it defines, their types, their relationships, their attributes and
Probably is something similar to what is described in the DOM Level 3
Abstract Schema as Arnold (thanks) suggested.
Is there any library implementing something like this ?
