Most of the time 1 would also want a custom content class with its own validation. JSON pages are handled by the content classes which derive from JCContent. The content class is responsible for parsing and validating raw text. JCContent does not do any validation beyond JSON parsing, but you may choose to derive from it and override JCContent::validate. Better yet, you may derive from the JCObjContent class which provides a number of validation primitives, and only override JCObjContent::validateContent
