Add PureXML.Validation.Schematron: compile a Schematron schema (matching schema/pattern/rule/assert/report by local name, so the ISO and legacy namespaces both work) and validate a document. A rule's context XPath selects the nodes it fires on; each assert/report test is evaluated relative to the node via the XPath context-node API. A failed assert is an error, a matched report a warning; within a pattern a node fires the first matching rule. Adds XPath.Query.nodes(over:) returning matched tree nodes so one tree can be queried repeatedly. Closes #52 Closes #53 Closes #25
