Apply LutaML models

There are several differences between previous content and model-based content:

• Previous content includes source blocks, but in model-based these are re-encoded in tables: Previous content: Model-based content:

• There are cases where source content from previous encoding is not equal to model-based content

• Likewise, there are cases where definition content from previous encoding is not same as model-based: Previous encoding:

  === Requirement
  Each normative statement which is tested by any conformance test is a requirement.

  Model-based content:

  class Requirement {
    definition {
      Normative statement that constitutes a requirement.
    }

• Also, there are a few cases where quotation rules are not fulfilled in model-based: Example:

  If class "a" is dependent on class "b", then to pass the test for...

  I think the "b", should be "b,". (As previous encoding.)

• In StandardizationTargetType class, there is no content in model-based. Which results in an empty sub-section.
