> emptyElementParsePolicy was a proposed extension to DFDL at the time we implemented it.
> However, it was accepted and is part of DFDL v1.0.
> Hence, we need to implement it as an official DFDL property, not just as an extension.
> Note that our extension dfdlx:emptyElementParsePolicy had enums 'treatAsEmpty' and 'treatAsMissing'.
> The official DFDL 1.0 property renamed 'treatAsMissing' to 'treatAsAbsent'.
> The meanings of the enums did not change.
> We should continue to accept the extension dfdlx property with the original enum values, and detect if both the official and extension properties exist and are in conflict.
> We should issue a suppressable warning about the extension property, suggesting upgrading the DFDL schema to use the official property. 
> The new official emptyElementParsePolicy should, if not defined, generate a suppressable warning, and get a default 'treatAsEmpty'.
