If there are SDATA, CDATA, or SUBDOC entity declarations in the internal subset, Arbortext Editor will, when writing an SGML document as XML, display the following warning message.

Warning. There is at least one CDATA, SDATA, or SUBDOC entity declaration in the internal subset. When saving the SGML document as XML, the entity type in the CDATA, SDATA, or SUBDOC entity declaration will be removed from the internal subset.

These entity declarations will be written to the XML file without their entity types. Also, Arbortext Editor escapes left angle brackets (< ) and ampersands (&) in CDATA entity values in the internal subset by writing the sequences &lt; and &amp; respectively.
