Section 2.4.4.3 & 2.4.4.4 & 3.2.1.2		
Technical	

Users expect that the sequence type expression element(name) means
element(name,*). Please redefine element(name) to be the same as
element(name,*) and introduce a special syntax for ISSD lookup and
substitution group inclusion. An example would be to use / in the schema
context path such as element(/name)
