I think it's bad idea to accept any data from users without any kind of input validation, that's poor design and may be dangerous too.
And I don't understand why markup data (user html) have to be represented as character data (CDATA). The better idea is to validate user input and fix up any errors at input stage and to well form that html by some html validator, take a look at HTML Tidy (tidy.sf.net) for example.
