What is the syntax for an IPS transformation condition to check if a property exists?

How do I check if $.emails is present? (not if it's empty)

Edit: this seems to work, but I'd like to see this documented:

$.emails EMPTY true

The blog doesn't mention the 'EMPTY' operator. All this info should ideally be on SAP Help.
