Hi DW,
Since XML and JSON has become more and more of an neccesity, the performance counter comment in the HTML is really getting annoying.
You can make both XML and JSON output by using standard templates, but the comment at the bottom messes everything up. (And if you hide it in default.aspx, you can't update the solution without it showing up again)
The comment shouldn't be rendered as default, but only when you ask for it, ie. via "stats=true" in the URL.
When you promote full design fredom, you can't print out random comments in the HTML, every bit counts :-)
The alternative is that you can disable the comment via an URL parameter. which would also work.
Regards
Martin
