IsPresent

The behavior of this function is dependent on the representation.

In XML and EDI, returns true if the Input Value argument is present in the document. That is if there is an element or attribute specified. This is different than the HasValue function in that this returns true if the element exists in the document but there is no text associated with the element.

For flat representations, returns true if the value for the element appears, or if the element is mandatory.

For database, always returns true, as all columns are present on the input. Like XML HasValue may or may not be true depending on if there is data present.
