The above description is ambiguous, and there is an interpretation of  
it according to which the above namespace attribute value is legal.  
The description would be better written as

   '.. The value of this attribute is either:
     1. the string ##any, or
     2. the string ##other, or
     3. a list of one or more of:
       a. a namespace URI
       b. the string ##targetNamespace
       c. the string ##local'

which is more accurate to the specification (XML Schema Part  
1:3.4.2), although even the specification looks odd (redundant  
parentheses etc which suggest that this was not the intended  
interpretation either).
