Assertion-based schema language. A way to test XML documents. Rule-based validation language. Cool report generator. Good for capturing edge cases.<\/p>\n
Same architecture as XSLT. (Schematron specifies<\/em>, does not perform<\/em>)<\/p>\n Demo. OxygenXML has support. Assert vs. Report – essentially opposites. Assert means “tell me if this if false”. Report means “tell me if this is true”.<\/p>\n “Almost as if Schematron is a harness for XPath testing.”<\/p>\n More examples:<\/p>\n Binding: Default is XSLT 1, but flexible enough to allow other query langauges via attribute @queryBinding at the top. Many processors allow mix-and-match between XSLT and Schematron. Examples showing just that.<\/p>\n Some tests can be very useful:<\/p>\n test=”every $line in tokenize(., $newline) satisfies string-length($line) le 72″<\/p>\n Q: What if the destination is not a human, but another part of a pipeline? Varies by implementation, but SVRL is standardized as an annex in the ISO spec, part of DSDL.<\/p>\n Use as little or as much as you want, at different times in the document lifecycle. “Schematron is a feather duster that reaches areas other schema languages cannot.” – Rick Jelliffe<\/p>\n As time permits section of the talk:<\/p>\n Other top-level elements: title, pattern, ns, let, p, include, phase, diagnostics.<\/p>\n -m<\/p>\n","protected":false},"excerpt":{"rendered":" Wendell Piez, Mulberry Technologies Assertion-based schema language.
