APPENDIX: The ddf Document Type Definition File for the Structure of Our XSLT (Document Type Definition) Model



The following text shows the d2d text type definition following the d2d ddf text type defintion mechanism to support xslt 1.0 input ([xslt1_0]) using the special xslt mode of d2d.

Please refer also to the automatically generated html documentation.


module xslt

// FIXME NO EFFECT  xmlns dyn = "http://exslt.org/dynamic"

XSLT, read as "Extensible Style Sheet Lanugage - Transformation",
is the central means for defining transformations on xml documents.
In co-operation with a special input mode of the d2d compiler,
this module allows a less verbose denotation of xslt programs for a certain back-end.
