Yes : http://msdn.microsoft.com/en-us/library/ms256100.aspx referenced
cause it's easier to read than the W3C docs which are impenetrable :

"The first URI reference in each pair is a namespace name, and the
second is the location of a schema that describes that namespace."

So you need both your namespace URI (the domain name will do) PLUS the
actual location of the schema document(s) which is a space separated
list

It's not necessarily assumed that the namespace URI is a valid URL, or
that the xsd location is a child of that URI/URL

It seems your schedule element below uses no namespace prefix, so
perhaps noNameSpaceSchemaLocation might be appropriate instead :
