    Description

      A user reports that his entirely binary format is getting an error that textOutputMinLength is required.

      Excerpt from email thread is below:

      .... I am getting strange error after I try to compile my schema:

      15:29:32.273 [main] DEBUG int_.nato.ncia.maniaccs.App - DFLD file's URL: jar:file:/home/luke/work/projects/mini-accs/socket-listener/target/data-socket-listener-1.0-SNAPSHOT.jar!/dfdl/asterix.dfdl.xml

      Non-default properties were combined from these locations:

      Schema context: element.CAT. Location line 1583 column 16 in jar:file:/home/luke/work/projects/mini-accs/socket-listener/target/data-socket-listener-1.0-SNAPSHOT.jar!/dfdl/asterix.dfdl.xml.

      (Note that I have been using the very same DFDL definition when running the TDML test that I have prepared)

      I checked the docs and, in section 13.2, it says that 'textOutputMinLength' is 'common to all simple types with text representation'; in my DFDL, there are no fields with such representation, I use only (unsigned) integers and bit flags.

      I checked the line in error message 'Schema context': it looks like this:

      <xs:element name="CAT" type="adatp-35:ushort8"/>

      while the 'adatp-35:ushort8' type is defined as follows:

      <xs:simpleType name="ushort8" dfdl:lengthKind="explicit" dfdl:length="1" dfdl:lengthUnits="bytes">
      <xs:restriction base="xs:unsignedInt"/>
      </xs:simpleType>

      Any help would be greatly appreciated!
