attr checkedButton conflicts with Google's material components library

[peterdk]

Since I upgraded to a more recent version of material compontents from Google, I fail now to compile this library.
Error is: CompoundContainers-1.1.3/res/values/values.xml:13:5-137: AAPT: error: duplicate value for resource 'attr/checkedButton'

Problem is that the material library has a 'checkedButton' attr added. Apparently these attrs are not namespaced or so. Since google's library is used a lot, it would be great if the property of this library could be prefixed or so, so it remains useable. Problem would be losing backward compatibilty I guess?
