XAML Regions Not Supported
NPP does not seem to honour regions for XAML, as documented at https://stackoverflow.com/questions/2888347/region-in-xaml/5163011.
<!--#region MyRegion--> <!-- Lots of XAML! --> <!--#endregion-->
should result in collapse/expand capability of the region, but does not.
Can this be implemented?
<!-- Lots of XAML! -->
Npp uses scintilla as a lexer for languages and avoids modifying
individual languages in order to make upgrading to a newer scintilla
version as easy as possible. This means that scintilla has to do it to be
added to npp one day
