Thanks for the summary as it crystalizes many of our discussions.  Some 
comments:

There were also a number of e-mails exchanged regarding the definition 
and structure of Controlled Subject Index and the definition of Subject 
Thesaurus and Controlled Term. I think there is still a concern about 
making Controlled Term a subelement of Subject Thesaurus.  I will 
telephone you to discuss this further.

Great.  Also, reverse the order of Linkage and Linkage Type which now 
comes first.

In an earlier e-mail I suggested a number of minor changes to align Cross 
Reference Linkage with Available Linkage. Will you be incorprating the 
following:

1. Revised definition for Cross Reference Linkage:

 Cross Reference Linkage (Repeatable):  This subelement is a grouping of
 subelements that together provide information needed to access the cross
 referenced object.  It is composed of the subordinate elements Linkage
 Type and Linkage.  Cross Reference Linkage is repeated for each new
 instance of Linkage Type.

2. Change Cross Reference Linkage Type to Linkage Type.  NO change to 
definition.

3. Add subordinate element Linkage after Linkage Type.

4. Revise the definition of Linkage:  This subelement provides the machine 
readable information needed  to perform this access.

This is such a condensed summary of the change I'm not sure I've 
understood it.  Is this what was agreed to:

Time Period (Repeatable)
    Time Period Structured (Repeatable)
           Start Date
           End Date
     Time Period Textual (Repeatable)
            Start Date
             End Date

The same structure would apply to Available Time Period, correct?

All this looks good to me.  I haven't found anything else missing. Please 
let me know if the suggestions I have made are acceptable.

Thanks again Eliot.
