DTD Fragment for XSLT Stylesheets (Non-Normative)
DTD Fragment for XSLT Stylesheets (Non-Normative)
NOTE: This DTD Fragment is not normative because XML 1.0 DTDs do not support XML Namespaces and thus cannot correctly describe the allowed structure of an XSLT stylesheet.
The following entity can be used to construct a DTD for XSLT stylesheets that create instances of a particular result DTD. Before referencing the entity, the stylesheet DTD must define a result-elements parameter entity listing the allowed result element types. For example:
<!ENTITY % result-elements " fo:inline-sequence fo:block ">
Such result elements should be declared to have xsl:use-attribute-sets and xsl:extension-element-prefixes attributes. The following entity declares the result-element-atts parameter for this purpose. The content that XSLT allows for result elements is the same as it allows for the XSLT elements that are declared in the following entity with a content model of %template; . The DTD may use a more restrictive content model than %template; to reflect the constraints of the result DTD.
The DTD may define the non-xsl-top-level parameter entity to allow additional top-level elements from namespaces other than the XSLT namespace.
The use of the xsl: prefix in this DTD does not imply that XSLT stylesheets are required to use this prefix. Any of the elements declared in this DTD may have attributes whose name starts with xmlns: or is equal to xmlns in addition to the attributes declared in this DTD.
