In parallel to the development of RELAX NG, two data-binding tools, namely 
Relaxer and RelaxNGCC were implemented.  Moreover, the designer (Hosoya-san) of 
XDuce (a functional programming language equipped with schemas as types) also 
contributed to the design of RELAX NG.  We also paid a lot of attention to 
boolean closure of schemas.

Relaxer, RelaxNGCC, and XDuce are completely different technologies.  I can also 
imagine some other data binding technologies or programming languages for RELAX NG.
If we incorporate mechanisms that are convenient for one particular style of data 
binding, we run the risk of blocking other styles.
