Datatypes
From UG

[edit] Intro
Datatypes are defined base on requirements, properties of the class of objects.
This encompasses "constraints". Normally system validates these.
In ZK there are separate widgets for some datatypes: "intbox", "decimalbox", etc.
! This could/should be defined often "before" the UI - this is a property of class of corresponding object. So in this case link should be provided instead of repeating definition.
When defining widgets there is a required attribute to be defined: datatype/format.
