While I appreciate the advantages of having the GILS profile compatible with 
the GEO profile, my initial reaction to the GEO profile structure is that it 
seems overly complex for the needs of GILS in general.

Could we not do something less complex, for example:

Time Period of Content (Repeatable)
    Time Period Structured (Repeatable)
           Start Date
           End Date
     Time Period Structured
            Start Date
            End Date
     Time Period Textual (not repeatable (all the applicable dates can be 
indicated)

At least one of the Start Date and the End Date would have to be supplied 
or both  to indicate a range.   Time Period Structured could be repeated 
if the range is not continuous or if there are muliple single dates, 
e.g. 1950 - 1963, 1967, 1969, 1971-1980.  This structure permits the 
provision of a single date, multiple dates and a range of dates.
