The saxon:next-in-chain attribute

The saxon:next-in-chain attribute (XSLT-only) is used to direct the output to another stylesheet. The value is the URL of a stylesheet that should be used to process the output stream. In this case the output stream must always be pure XML, and attributes that control the format of the output (e.g. method, cdata-section-elements, etc) will have no effect. The output of the second stylesheet will be directed to the destination that would have been used for the first stylesheet if no saxon:next-in-chain attribute were not present.

This serialization property is available only on xsl:output declarations. It cannot be supplied as an attribute to xsl:result-document or in any of the various APIs that control serialization.

Supplying a zero-length string is equivalent to omitting the attribute, except that it can be used to override a previous setting.
