You might find Saxon's error message more helpful:

Error at xsd:all on line 9 of file:/c:/temp/test.xsd:
  Within <xs:all>, an <xs:element> must have @maxOccurs equal to 0 or 1

See Schema Part 1 §3.8.6, constraint "All Group Limited", rule 2.

This rule is lifted in XML Schema 1.1, and this feature of XML Schema 1.1
will be implemented in the next Saxon release.
