[eml-dev] access in PhysicalDistributionType

[Margaret O'Brien]

Hi all -
by now you've probably seen the messages from cvs and bugzilla, but here 
it is one more time: I made a small but crucial change to the 
PhysicalDistributionType:
Way back, when I added the optional <access> element to this type, I put 
it in a xs:sequence group. This was wrong -- it should have been a 
xs:choice. So it meant that <access> could have had a sibling 
<references> -- very bad. 

So the correct instances are this:
<distribution>
    <references>my-data</references>
</distribution>

or this:
<distribution>
    <online>
       ...etc ...
    </online>
    <access>
        ...etc ...
    </access>
</distribution>

IF you used a revision of eml-physical.xsd earlier the one just checked 
in (r1.75), you would have been allowed to create this bad EML:
<distribution>
    <references>my-data</references>
    <access>
    ...
    </access>
</distribution>

Which just isn't right. Sorry - I did not see this until I started 
transforming documents and say how convoluted they would become.

Margaret
