These are the beginnings of something that could become an XPath 3.1 implementation in Rust. It is alpha-quality software.

• git submodule update --init
• Install Rust stable using rustup
• cd smop-qt3tester
• cargo run -- catalog.xml This will run tests from the XQuery/XPath test suite.
• edit catalog.xml to enable other tests, or add new ones from qt3tests/catalog.xml
• smop-xpath is the main library. The API is unstable
• smop-xmltree is the XML document model that's used by smop-xpath. It is derived from roxmltree.

• https://www.w3.org/TR/xpath-functions-31/
• https://www.w3.org/TR/xpath-datamodel-31/
• https://www.w3.org/TR/xquery-semantics/ (not a standard, still useful)
• https://www.w3.org/TR/xmlschema-1/
• https://www.w3.org/TR/xmlschema-2/
• https://www.w3.org/TR/xmlschema11-2/

The runtime data model (smop_xpath::xdm) is currently an enum and doesn't store runtime types. The compile time types also don't do much. I don't know what the best data structure for xdm items would be. enum? structs? traits? some combination of those?

The name SMOP (small matter of programming) came about because I still own the smop.org domain, which doesn't run a website at the moment.
