Not really sure where “File Identifications” lives and how and why you need to set it, but if you use agent to generate XML, you should first print http headers, then the rest of your output:’ print header(s)
Print “Content-type:text/xml”
’ print one empty line to tell Domino that the header is done (it will probably understand it anyway, but just in case)
ok, right. Of course, your agent has nothing to do with this. It’s the XSL file that do not have a correct Mime type. So it depends how your colleague is providing this XSL.
In your case it looks like it’s some page or another agent as it has the same path as an agent (unless you use some kind of mapping/redirection). It definitely is not a file in filesystem. So if it’s a page you just set Content type, Other text/xml, else could you explain how do you provide this XSL file.
Not clear what you call “a page”; if it’s a page as “design element Page” then you should be able to fix it as described in my previous answer.
If it’s a Notes document you open using a form, then you can modify the form it gets rendered with; on propeller-hat tab you can enter Content type property for a form.
