#TargetType.TaggedValue	CommaSeparatedExampleValues	Short Description
#Span.Eco.UIAllowed	True,False	Disables a ViewModel to be accessed within the UI (default True)

#Span.Eco.UIAllowed is true by default. If you set it to "False", a user cannot reach that page. It is usually used in conjunction with the Rest pages - RestAllowed default true and UIAllowed default false - meaning that the page can only be called by Rest because you do not want a user to see your Rest APIs in all cases.
