Allow for Apache-2.0 License in metainfo

[awarnke]

Hello,

Currently, there is an error report for project https://tracker.debian.org/pkg/crystal-facet-uml

stating
"
metainfo-license-invalid
The MetaInfo file does not seem to be licensed under a permissive license.
"
but Apache-2.0 should be pemissive enough (see http://spdx.org/licenses/ ):

crystal-facet-uml
<metadata_license>Apache-2.0</metadata_license>
<project_license>Apache-2.0</project_license>
see https://github.com/awarnke/crystal_facet_uml/tree/master/installation_linux

Could you allow this type of License-information?

Kind Regards
Andreas

Checking issue #195 i guess i start understanding the bug:
Only the <metadata_license>MIT</metadata_license> needs to be adapted, not the <project_license>Apache-2.0</project_license> ?
The Error message seems to state this - maybe it helps making this more clear in the error message text?

I see that you need the MIT License for this file.

Is it possible to provide the metainfo.xml under two licenses:
MIT for appstream purposes
and Apache-2.0 to avoid the lintian-checker bugs due to mismatches between metainfo.xml and debian/copyrights ?
