Property:Summary

This property contains the Has type::text summary of a referenced item, for display within lists or trees. It may contain wikicode, although square brackets do not seem to work when using the property::value syntax; use the syntax instead.

Type="Text" is usable but not quite right. Wikicode displays correctly in the footer of the page using this property, but displays in raw form on the property page's listing of pages using it.

Type="String" seems to be identical, except that it has a 255-character length restriction (which isn't likely to be a problem, but doesn't confer any useful advantages for this property).
