A from-scratch XML implementation, loosely modeled on the [spec](https://www.w3.org/TR/2006/REC-xml11-20060816). Features: - Supports enough of the XML 1.0/1.1 spec to handle the 99.9% of XML documents in common current usage. - Simple to understand and use. Small. Caveats: - We do NOT support HTML in this package, as that may or may not be valid XML. If it works, great. If it doesn't, that's not considered a bug. - We do NOT support UTF-16. If you have a UTF-16 XML file, please convert it to UTF-8 first. Also, our condolences. - <[!ELEMENT and <[!ATTLIST are not supported, and will be either ignored or return an error depending on the parser options. TODO: - Optional CDATA unboxing. - Optional `>`, ` `, ` ` and other escape substitution in tag bodies. - Test suite MAYBE: - XML writer? - Serialize/deserialize Odin types?
