Hi,
It would be great if it was possible to insert comments in templates, and these comments was not outputted to the client. How about introducing this new tag couple:
<!--@CommentStart--> This is my comment that will not be outputted to the client :-) <!--@CommentEnd-->
When DW parses the tags is should remove everything: starttag, comment and endtag. It would be nice if no empty lines were left from the comments (when using the Snippets tag DW leaves at least one empty line for each snippet in the page).
