It probably is.  There are those who think 
declaring an xsd:list saves them from the 
fact that it is just whitespace delimited 
CDATA.  In a sense, some don't quite get it 
that Schemas and DTDs are instructions to 
application processors, not parsers, and 
even then, don't declare the delimiters 
inside the attributes.  One might want to 
rethink this

but at the end of the day, a list inside an 
attribute where the content of a list member 
includes whitespace is back to ugly syntax 
hacking in the instance.

If you have to stick them in attributes, URL-escaping seems like the 
best solution to me. It's easily describable with WXS and you have 
precedence: xsi:schemaLocation. Think of your attribute as containing a 
list of URIs, relative in this case.

That is the better solution, isn't it?
