GCPM's string-set property and the string()/content() functions had no support. Add StringSetProperty with a StringSetValueConverter parsing "[ <custom-ident> <content-list> ]# | none" (content-list items being a <string>, counter()/counters(), content(), string() or attr()), plus ContentFunctionConverter (content()/content(text|before|after| first-letter)) and StringFunctionConverter (string(name) with an optional first/last/start/first-except keyword). Both functions are also accepted inside the content property.
