- use dict instead of array (no need to unset first)
- use size of field from apm::package_version::attributes::get_spec if provided
- add size and xml formatter to apm parameter spec
- add configurable xml formatter that is able to handle multiple entries and value-coding in attributes
- regenerated info file to check, if "initial-install-p" persists - seems fine.
- use dicts to avoid extra arrays
