# Features

- Exporting a log ?? 
    - a progress bar for exporting?

- helpful error messages for reader
    - what attribute
    - what event #
    - what trace #
    - to encourage helpful repair

- decorators 
    - debug parameter to turn on and off logging

- validate XML files output by lib against XSD schema for XES
    - appears that BPIC logs and OpenXES do not conform to the schema
    - mostly due to extra attributes
    - find a way to resolve this by possibly 
        1. ensuring our output strictly validates
        2. creating a patched XSD schema that accomodates OpenXES and the BPIC logs
    - probably follow Postel's principle: be strict in what we emit (conform to XES schema) but tolerant in what we accept (deal with variants, don\'t choke
