    * Breaking
      - The methods of `TextCodec<T>` now have `&self` receivers. This also
        implies that `#[xml(text(codec = ..))]` now takes expressions instead
        of type paths.

        Because all implementations provided by `xso` were in fact unit
        structs, this should not change most invocations, with one exception:
        The type argument of `Base64` was removed. Replace all `Base64<Foo>`
        references with `Base64.filtered(Foo)` to update your code.

        This change overall allows for more flexibility in the implementation
        of text codecs.
    * Added
      - Support for child elements in derive macros. Child elements may also
        be wrapped in Option or Box or in containers like Vec or HashSet.
      - Support for overriding the names of the types generated by the derive
        macros.
      - Support for deriving FromXml and AsXml on enums.
      - Support for extracting data from child elements without intermediate
        structs.
      - Support for collecting all unknown children in a single field as
        collection of `minidom::Element`, or one unknown child as a
        `minidom::Element`, or zero or one unknown children as an
        `Option<minidom::Element>`.
      - Support for "transparent" structs (newtype-like patterns for XSO).
      - FromXmlText and AsXmlText are now implemented for jid::NodePart,
        jid::DomainPart, and jid::ResourcePart (!485)
      - Support for optional child elements, the presence of which are
        translated into a boolean (`#[xml(flag)]`).
      - Generic TextCodec implementation for all base64 engines provided by
        the base64 crate (if the `base64` feature is enabled).
      - New `codec` field on `attribute` meta, to support decoding and
        encoding using any `TextCodec`.
      - Support for `no_std` usage (the alloc crate is required, though).
      - Add a PrintRawXml helper struct to be able to display raw xml, useful
        for debug logs.
    * Changes
      - Generated AsXml iterator and FromXml builder types are now
        doc(hidden), to not clutter hand-written documentation with auto
        generated garbage (something certain big tech companies could take
        an example of, honestly).
