<xi:fallback> XInclude Fallback

To quote the XInclude Recommendation, “the <xi:fallback> element appears as a child of an <xi:include> element. It provides a mechanism for recovering from missing resources. When a resource error is encountered, the <xi:include> element is replaced with the contents of the <xi:fallback> element. If the <xi:fallback> element is empty, the <xi:include> element is removed from the result.”


Since it is not the business of this Tag Set to specify processing, the <xi:fallback> element will default to #PCDATA, but the parameter entity for the fallback-model can be redefined in a NISO STS customization for any standards-producing organization that desires a different fallback result.
