Hello DFDL community,
Question #1: Is the following statement true or false? The decision on what properties to include in DFDL were driven by real-world use cases - that is, by real-world data formats. Question #2: Is the following statement true or false? Upon examining the real-world data formats, the DFDL working discovered that it is rare to have anything other than an empty string as the in-band nil value in a complex type; because of it's rarity (yesterday Mike used the word "obscure"), the DFDL working group decided to restrict in-band nil values on complex types to the empty string. Question #3: Is the following statement true or false? For every DFDL property there are multiple real-world data formats which require that DFDL property. Question #4: Is there a document which shows the mapping between DFDL property and real-world data formats requiring that DFDL property? /Roger
