Nested class names aren't handled when expanding substitution rules.

You can't use @ClassName in a substitution lookup if the class is defined in terms of other classes. So this works

lookup InsertKashida { sub @SubClass1 by @SubClass1 kashida-ar; sub @SubClass2 by @SubClass2 kashida-ar; } InsertKashida;

but not this:

lookup InsertKashida { sub @TheClass by @TheClass kashida-ar; } InsertKashida;

where @TheClass is fined in classes.xml by:

<class name="TheClass> @SubClass1 @SubClass2 </class>

This feels very uninituitive to me. The FEAX code shouldn't be affected by how the class is defined.

It seems to make a difference whether the class is defined in classes.xml or in the FEAX file. When it is in the FEAX file, it works okay.
