### Features

- Complete support of paths, so data like `M10-20A5.5.3-4 110-.1` will be parsed correctly.
- Implicit path commands will be automatically converted into explicit one.
- Some SVG2 data types support.
- Pretty fast.

### Limitations

- Accepts only [normalized]https://www.w3.org/TR/REC-xml/#AVNormalize values,
  e.g. an input text should not contain `&#x20;` or `&data;`.
- All keywords must be lowercase.
  Case-insensitive parsing is supported only for colors (requires allocation for named colors).
- The `<color>` followed by the `<icccolor>` is not supported. As the `<icccolor>` itself.
- [System colors]https://www.w3.org/TR/css3-color/#css2-system, like `fill="AppWorkspace"`,
  are not supported. They were deprecated anyway.

### Safety

- The library should not panic. Any panic considered as a critical bug and should be reported.
- The library forbids unsafe code.

### Alternatives

None.
