The X-Machine evaluates the media type settings specified in the Content-Type field of an incoming HTTP request. It distinguishes between text and binary documents. A text document can be an XML document or a non-XML document. A binary document can only be a non-XML document.

The distinction between XML document, non-XML text document and binary document is made according to the media type as shown in the following table:

Media type	Type of Tamino Document
*/xml or */*+xml, for example: application/xml text/xml image/svg+xml	text, XML document
text/* (other than text/xml) application/rtf	text, non-XML document
nothing or blank	text, XML document
All other media types	binary document

XML documents are handled according to their Tamino schema definition, if it exists (Tamino also allows the storage of XML documents without a matching schema definition). This includes validating against the information stored in Tamino's Data Map and indexing according to the tsd:physical settings in the schema.

Notes:

1. The Tamino data loader uses special rules for determining the media type settings. See the section Known Media Types in the data loader documentation for details.
2. Tamino schema definitions can be defined for non-XML documents.
