Get all LMS Occurrences on offer during a date range. 

Returns an Authenticated Occurrence List containing all of the LMS Occurrences, which overlap the given date range. 

Each Occurrence is represented by a TOccu. The collection of Occurrences is represented by a List of TOccu. 

A token is passed for authentication. If the authentication fails, or other errors occur, no occurrences are returned. The result of the authentication is represented by a TAuthenticate object. 

A date range is passed as two parameters, xsdStart and xsdEnd, which define the end points of the date range. An occurrence will be returned in the Occurrence List, if any date for which the occurrence is offered (from its startdate to its enddate) co-incides with any date in the date range (including end points). 

Requires a valid registration key entry for the Short Courses feature. 

This function has security level "Protected", and can only be accessed by users that have explicitly been granted permission to the API.
