As I've already been burnt by this as previously reported, please begin using a simple convention to make things clearer -- like all plain old datatypes (POD) should be displayed in lowercase only.

Pseudo-datatypes are fine (e.g., url is a textstring that forms a W3C URL).
Text would become text. Classes would continue to be named just as they are.

No one should have to un-learn all their previous experience in order to use schemas successfully, conceptually not unlike the Don't Make Me Think and Keep It Simple, Stupid (KISS) approaches.

Although I'm creating an issue for it, this problem has certainly bitten other people as well.

Simplicity resolves complexity.
