Enter PML Expressions

A number of rule definitions include PML expressions.

A PML expression field may be too short to conveniently enter a long PML expression. Therefore, at the end of PML expressions fields there is a ... option. Selecting this opens the Edit Expression dialog in which the PML expressions may be entered.

PML expressions are automatically validated on entry. If a PML expression is valid (or if the field is blank), a green tick is displayed at the beginning of the PML expression entry field. If a PML expression is invalid, a red tick is displayed.

If a rule contains an invalid PML expression, the rule will not be applied.
