Every xsl and xml file that Civil 3D comes with as a template can be difficult to build on, as they are provided.
I would like to see the schema for these files published and linked from within the root node (as is standard xml practice) so that we can use an intellisense enabled IDE to make it easier to build on these files or to create our own.
It would be great if the schema would have documentation tags to help the users understand what each node is intended for.
