Evaluate Mime-Type and File Extension

Natural Web Interface holds an own table for mime-type / file extension settings. This table is saved in the Natural text member MIMETYPE. The text member contains pairs of mime-type names and file extension(s):

    text/html     html htm
    text/plain    txt
    text/xml      xml
    text/richtext rtf

W3MIME-TYPE reads the internal table and offers the following translations:

• Evaluate a mime-type for a given file extension.

• Evaluate a file extension for a given mime-type

The functionality is used internally at the W3LOAD-RESOURCE subprogram.
