▪Sub-Namespace:

Most types of picker item (Select-button, command-button, attr-Button, slider) may contain a sub-namespace if it is set durning the designing process.

A sub-namespace is an addition to picker namespace.

Say your picker namespace is set to "myCharacter", and there is a select-button has the sub-namespace "bodyRig:chestRig", the select-button contain a member called "chest_ctl", then the final maya control will turn out be this:

 myCharacter:bodyRig:chestRig:chest_ctl;

This means when you click this select-button in animator mode, the tool will try to select "myCharacter:bodyRig:chestRig:chest_ctl" in maya scene.
