Using expressions in EMX

Introduction
For some entity type attributes an expression can be set that determines whether or not a condition is true based on the attribute values to determine whether values are valid, visible or required.
Examples
The following expression returns true when the value of attribute 'myAttributeName' of an entity only contains alphanumberic characters:
regex('^[a-zA-Z0-9]+$',{myStringAttributeName})
In this example:
{myStringAttributeName} looks up the value of the myStringAttributeName variable
regex is a function
You can combine expressions to perform more complex logic:
{myIntAttributeName} > 3 and {myIntAttributeName} < 6
Reference
See molgenis/molgenis-expressions for a complete description of the syntax.
