#type_with_namespace(register, namespace_uri = nil) ⇒ Class?

Get type with namespace-aware resolution.

Uses the register’s resolve_in_namespace method for version-aware type resolution. Falls back to standard resolution if no namespace or register is provided.

Parameters:

  • register (Lutaml::Model::Register, Symbol, nil) —

    The register or register ID

  • namespace_uri (String, nil) (defaults to: nil) —

    The namespace URI for version awareness

Returns:

  • (Class, nil) —

    The type class or nil

Check if the value to be assigned is valid for the attribute

Currently there are 2 validations

1. Value should be from the values list if they are defined
   e.g values: ["foo", "bar"] is set then any other value for this
       attribute will raise `Lutaml::Model::InvalidValueError`

2. Value count should be between the collection range if defined
   e.g if collection: 0..5 is set then the value greater then 5
       will raise `Lutaml::Model::CollectionCountOutOfRangeError`
