Export stylesheet packages

Export stylesheet packages

XSLT 3.0 packaging allows stylesheet modules to be independently compiled and distributed, and provides much more "software engineering" control over public and private interfaces, and the like. The ability to save packages in compiled form ("stylesheet export file", SEF) gives much faster loading of frequently used stylesheets, and also enables in-browser execution using Saxon-JS.

Reading W3C schemas and DTDs

Reading W3C schemas and DTDs
