+.vindex &$mime_content_description$&
 This variable contains the normalized content of the &'Content-Description:'&

 implementations repeat the filename for attachments here, but they are usually
 only used for display purposes.
 
 .vitem &$mime_content_disposition$&

 This variable contains the normalized content of the &'Content-ID:'& header.
 This is a unique ID that can be used to reference a part from another part.
 
 .vitem &$mime_content_size$&
+.vindex &$mime_content_size$&
 This variable is set only after the &%decode%& modifier (see above) has been
 successfully run. It contains the size of the decoded part in kilobytes. The
 size is always rounded up to full kilobytes, so only a completely empty part
 has a &$mime_content_size$& of zero.

 This variable has the value 1 (true) when the current part has the main type

 Since multipart entities only serve as containers for other parts, you may not
 want to carry out specific actions on them.

 This variable is a counter that is raised for each processed MIME part. It
 starts at zero for the very first part (which is usually a multipart). The
