WS-I Compliance Tool does not support Soap 1.2 protocol in WSDL

I'm trying to test our WSDL for WS-I compatibility with the 1.1 Compatibility Testing Tool that ships with SoapUI (pro or otherwise, 4.6 - 5.1), but a related tool since 2005 when the Soap 1.2 protocol wasn't around.

This causes multiple statements to fail in the report generation, namely BP2032 and BP2402, and several other mandatory failures (BP2012, BP2017, BP2117, etc.). After examining some of these assertion errors, it seems that they are not valid at all as the WSDL does indeed match the description of each item. We don't have a Soap 1.2 specific feature in WSDL (only use a requirement-based namespace). If I go back to Soap 1.1, WS-I Compliance (SoapUI) passes all claims.

The WS-I.org website offers a new addition to the tool profile, but it looks like it's just XSLT with no instructions on how to run them (no Java time) - BSP 1.1 Test Tools . My question is, how can I validate WSDL against WS-I (in SoapUI) when Soap 1.2 is used?
