> Extend C code generator to support hexBinary elements
> -----------------------------------------------------
>
> Key: DAFFODIL-2566
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2566
> Project: Daffodil
> Issue Type: New Feature
> Components: Back End C-Generator
> Affects Versions: 3.1.0
> Reporter: John Interrante
> Assignee: John Interrante
> Priority: Blocker
> Fix For: 3.2.0
>
>
> Allow Daffodil to generate C code from DFDL schemas using the type
> "hexBinary" for fixed length and prefixed length opaque byte arrays.
> The "hex" simply means that the binary 8-bit bytes are represented by
> hexadecimal characters in the XML infoset and the C code knows how to
> convert between these binary and text representations when parsing
> binary bytes or unparsing XML infosets. Add hexBinary elements to the
> ex_nums test schema to exercise the new code.
