Encoding considerations: Binary or base64 required

Security considerations:

        As of this writing, KFormula documents do not contain any active
        content. As such, it is believed that usage of this mimetype
        does not introduce security concerns other than those already
        inherent in ZIP archives, XML files and supported image files.

        It is expected that later versions of KFormula feature scripting
        and macro recording facilities. It is, however, not intended
        to include active content into the KFormula document itself.

        KFormula documents include document metadata such as the name of
        the author, etc. However, none of this data is written
        automatically. The KFormula user has full control over what
        metadata is to be included and must actively request the
        inclusion. As such, the use of this mimetype does not lead to
        hidden leaking of possibly sensitive data.

Interoperability considerations:

        Earlier versions of KOffice (<= 1.1) used gzip-compressed UNIX
        tar files as archive format. It is expected that this obsolete
        format will die out soon after the first release of KOffice
        1.2. Thus, this registration does not apply to the obsolete
        format. Implementations are expected to use the old
        application/x-kformula mime type for the obsolete format.

Published specification:

        A KFormula document consists of a series of XML streams and
        externally generated content which are bundled together as a
        ZIP archive.

        Any content placed in KFormula can either be completely embedded
        in the KFormula document or can be linked to using URIs.

        A description of the storage format is contained in the source
        code distribution (lib/store/SPEC). The current version can be
        obtained online via KDE's WebCVS interface:

Applications which use this media type:

        All applications in the KDE KOffice Office Suite, esp. KFormula.
