Hi Thomas,

To be honest, I am really confused about what you are trying here :)

Do you mean ArcExplorer will produce errors?  Or are you saying that 
Mapserver is producing debug statements in the XML output saying that you 
need more METADATA entries in your .map file?

This is a problem.  Are you certain that your php header() call is the 
first thing that is in your .php file?   If you have an empty line, then 
that will constitute output and you can't resend headers...

Perhaps someone on the list can or I can.  Please gzip/zip and attach :)  
I believe your problem is #3 though...

Good luck,
