+
+oxsdatatypes is an implementation of some [XML Schema Definition Language Datatypes](https://www.w3.org/TR/xmlschema11-2/).
+Its main aim is to ease the implementation of SPARQL or XPath.
+
+Usage example:
+
+```rust
+use std::str::FromStr;
+use oxsdatatypes::Decimal;
+
+assert!(Decimal::from_str("22.2").unwrap() > Decimal::from_str("21").unwrap());
+```
