Add the PureXML.XInclude namespace: RFC 3986 reference resolution (URIReference with dot-segment removal) and an xi:include processor over the value tree. href resolves against the base and in-scope xml:base; parse=xml includes the document element or an xpointer() fragment (via PureXML.XPointer), parse=text includes raw text, and a failed load uses xi:fallback or errors. Includes nest. No I/O is done internally: fetching is only through the injected loadingURI closure, so the default fetches nothing. Closes #48 Closes #49 Closes #50 Closes #51 Closes #24
