The documentation for ArcGIS SDK version 100.3 states that it supports OGC WMS version 1.3.0. Does it also support the older version, 1.1.1? It is unclear. I see that SDK version 100.5 supports both 1.1.1 and 1.3.0, but don't want to upgrade unless necessary, as that will also mean upgrading to a newer version of Qt.
