SM raised the issue of <gap>, which was not really handled properly, but which is needed. This is what we've done:

• Copied the values from <supplied>/@reason to <gap>/@reason in the schema. These two attributes are defined directly on their elements, but their definitions are currently duplicated and we expect to keep them in sync.
• Made @reason mandatory on both <supplied> and <gap>. This resulted in a few validation errors in mayoral shows, which SM will fix.
• Added handling for <gap> to the XSLT (tested on dev and ported to live). The reason is expanded using boilerplate text into a title attribute, and the gap element itself is replaced by an ellipsis in square brackets.

SM will ask TL to add documentation for <gap> to Praxis.
