Re: What do these error messages mean? (xmldsig schema)

I've fixed the errors below and a number of other stupid mistakes. These 
mistakes result from the way I'm used to thinking about schema whereby in 
order to make an element and its type re-usable, I defined an element name 
*and* its type as seperate global definitions. In RelaxNG, the examples I 
read typically include element name is part of its definition... For 
example,

  ...<ref name="AddressBook"/>
  <define name="AddressBook">
    <element name="addressBook">
      <zeroOrMore>
        <ref name="Card"/>
      </zeroOrMore>
    </element>
  </define>

whereas I'm partially emulating my schema approach:

  <element name="addressBook"><ref name="AddressBook"/></element>
  <define name="AddressBook">
      <zeroOrMore>
        <ref name="Card"/>
      </zeroOrMore>
  </define>

and this resulted in some confusion for me, which has now been remedied. (Of 
course, doing a relaxNG without concern about schema would be more 
straightforward...) Next step: have the xenc rng borrow from the xmldsig 
rng! <smile/>
