Currently the Import AIXM 5.1 to AIS Data Interoperability tool is configured to look at a XML file as the source and not the WFS. Since the tool is currently built on the Data Interoperability extension, the WFS is restricted to the release of the underlying technology (namely FME from Safe Software). In the latest release FME 2014, I believe WFS 2.0 is now a supported format and it does have the ability to read and construct features if it is in the AIXM 5.1 schema. Unfortunately though this will only allow you to read in the data in a different ETL tool and a new ETL will have to built in order for you to map those constructed features to the AIS datamodel. I =t might be possible to re-use the existing workbench to read from the WFS rather than an xml. Will all your data be coming from a WFS or will you still need the ability to read from an XML file?
