Feedback received by us from CoreFilng:

If INF is used as the value of the 'decimals' attribute on facts in an instance, this exposes a fault in the COREP taxonomy. A custom XII Formula function defined in the taxonomy (iaf:precision in
interval-arithmetics.xml) incorrectly assumes that XBRL precision attributes are always decimal numbers, hence the use of INF causes formula/assertions executing this function to fail with error XPTY0004 (XPath type mismatch) on such facts.

This has come to our attention through extended testing and did not show up in the initial single day we had to report feedback because none of the EBA supplied sample instances (which we tested) have facts reported with INF precision.
