What is it?
A validation rule specifies the condition(s) the value of the Attribute has to meet in order to make it a valid entry. The outcome of a validation rule is always true, false or unknown (Boolean).
A validation rule passes if the outcome is true or unknown.
When do validation rules apply?
Validation rules apply when:
- connected to an attribute, AND
- the attribute is put on a page AND
- the attribute is not read-only AND
- the page is submitted.
Validations are also triggered upon "refresh" (see Containers).
Validations only block progression to another page if the Attribute is placed on the Page as "Required" and the validation is set to "Blocking" (see below).
Validation types
Several predefined, more complicated validations are automatically imported into Blueriq projects (they are defined in the AquimaLibrary library). These are documented on the page for Validation types.

In the example the message and expression do not match. A 18 year old will be evaluated to false (18 > 18 instead of 18 >= 18) but the message displays as at least 18. This is a bit confusing, I believe.
