OxRdfXml is a parser and serializer for [RDF/XML](https://www.w3.org/TR/rdf-syntax-grammar/).

Usage example counting the number of people in a RDF/XML file:
```rust
use oxrdf::{NamedNodeRef, vocab::rdf};
use oxrdfxml::RdfXmlParser;

let file = b"<?xml version=\"1.0\"?>
<rdf:RDF xmlns:rdf=\"http://www.w3.org/1999/02/22-rdf-syntax-ns#\" xmlns:schema=\"http://schema.org/\">
 <rdf:Description rdf:about=\"http://example.com/foo\">
   <rdf:type rdf:resource=\"http://schema.org/Person\" />
   <schema:name>Foo</schema:name>
 </rdf:Description>
 <schema:Person rdf:about=\"http://example.com/bar\" schema:name=\"Bar\" />
</rdf:RDF>";

let schema_person = NamedNodeRef::new("http://schema.org/Person").unwrap();
let mut count = 0;
for triple in RdfXmlParser::new().parse_read(file.as_ref()) {
    let triple = triple.unwrap();
    if triple.predicate == rdf::TYPE && triple.object == schema_person.into() {
        count += 1;
    }
}
assert_eq!(2, count);
```
