EPSG support with WMS 1.3 for CITE tests

In testing our WMS 1.3 service, it appears that support of CRS:84 is required in order to pass the tests. However, from reviewing the WMS 1.3 spec, it appears that the use of EPSG:4326 and other EPSG:xxxx codes is still valid. Can you comment on this?

From the CITE testing site:
Must contain the test dataset in layers that are subsetable and resizable and support CRS:84.
The CRS:84 support must be precise up to the ten-thousandth of a degree.
