US-GAAP Elements used in IFRS Filings

Rule function

This rule identifies where filers have reported a US-GAAP element in an IFRS filing. The rule has two components. The first checks where a US-GAAP fact has been reported and the second identifies where a US-GAAP element has been used in the presentation linkbase. The rule identifies those elements that have a namespace that contains the string ''http://fasb.org/us-gaap/'.
If an element has this namespace then an error will be produced for the concept used as well as any facts that have been reported that a use a primary concept from the US-GAAP namespace.

Problem solved by the rule

The rule identifies where filers have inadvertently included the US-GAAP taxonomy in an IFRS filing and have used incorrect elements.
