/// Defines serialize and deserialize functions to handle "collect" XML nodes like this:
/// ```xml
/// <FixtureType>
///     <Revisions>
///         <Revision />
///         <Revision />
///         <Revision />
///     </Revisions>
/// </FixtureType>
/// ```
/// can become:
/// ```text
/// FixtureType {
///     revisions: [ Revision, Revision, Revision ]
/// }
/// ```
///
/// Can also handle multiple collect nodes, appending them into a single list:
/// ```xml
/// <FixtureType>
///     <Revisions>
///         <Revision />
///     </Revisions>
///     <Revisions>
///         <Revision />
///     </Revisions>
/// </FixtureType>
/// ```
/// can become:
/// ```text
/// FixtureType {
///     revisions: [ Revision, Revision ]
/// }
/// ```
