Defining Field Rules

Field rules define the behavior and constraints on fields. Field rules are additional elements that are listed inside <FIELD></FIELD> blocks. For example, if a field is required, the XML that defines the field might look as follows:

<FIELD refname="System.Priority" name="Priority" type="String">
<HELPTTEXT>Enter the business priority of the bug</HELPTEXT>
<REQUIRED />
</FIELD>
