14.3.4 Specifying the root element and content type
The default value for root is doc for generic XML. Because XML does not have <head> and <body> sections, the default is to omit these:
; ContentType = text/html (default for HTML and XHTML)
; or application/xml (default for XML); try not to use text/xml
Content-Type is part of MIME, and is used by document-processing tools. Unless you know exactly what you want and need only a mechanism to specify it, leave this setting alone. For more information, see:
