What Is Standard Extension for External Entities References in an XML Document?
Question Is there a standard extension (other than .xml or .txt) that should be used for external entities which are being referenced in an XML document. These external entities are not complete XML files, but rather only part of an XML file, starting with the ]]> B.xml: ]> &htmlComment; Currently we are using .txt as an extension for all such entities, but need to change that, otherwise the translation team assumes that these files need to get translated, whereas they don’t. Is there a standard extension that we should be using? Answer I marked up your DTD syntax in “red (bold)” in your DTD.
