after you add the specific (explicitly defined in XSD) properties, run:

/subsystem=modeshape/repository=sample/source=git/:write-attribute(name="properties", value=[{"directoryPath" => "abc"}])

if you want to add other "generic" Git connector properties, use the value=[{"name" => "value", "name => "value", etc}] format.

Also note that 4.6.0.Final will most likely *not work* with Wildfly 10. This will be supported only starting with ModeShape 5.

The XSD is always located in %JBOSS_HOME%/docs/schema if you've extract the ModeShape DV WF kit.

ModeShape 4.6.0.Final is the final 4.x community release and still uses Java 7. Willdfly 10 requires Java 8 so the ModeShape WF subsystem from 4.x will not run on Wildfly 10. ModeShape 5 will require Java 8 and the WF subsystem will therefore work with WF 10.
