And once you have the answer to how much validation is possible,
you have to know where and when that is possible. For example,
does a handheld have the resources needed to use XML Schema
Schemas are a lynchpin of services as I understand them. If so,
how and where to apply them and where the environment
enables them to be applied is good stuff to know before one
sits down to build a cell phone app. For instance, can anyone
tell me which devices support IE5.5 and which require me to
default to less powerful frameworks? Is it a good idea
to rely on Schemas for field level validation (say when
tabbing out of the field (no, but it's an interesting question))?
Even better... Schematron assertions or fieldNameValue=this code?
