<foreign>
The <foreign>
element allows the introduction of non-DITA content, for
example, MathML, SVG, or Rich Text Format (RTF). The <foreign>
element
or a specialization may contain more than one type of non-DITA content or a mix of DITA and
non-DITA content. Specialization of the <foreign>
element generally is
implemented as a domain, but architects looking for more control over the content may
implement foreign vocabularies as structural specializations.
