EducationContent choice uses inline sequence of elements

Summary of outcomes for Data Standard 2.1

• Problem Addressed: MetaEd does not support the inline listing of child elements of a choice directly within the entity, as is presently the case with the LearningResourceChoice referenced in EducationContent.
• High-level Reasoning: The EducationContent domain entity includes a choice (LearningResourceChoice) between providing the LearningResourceMetadataURI or providing a series of other properties to describe the learning resource. Presently, the series of other properties are not contained in a common type. This is not supported by MetaEd.
• Changes Made: Created new inline common type LearningResource to contain the alternate group of properties used to define a learning resource if a LearningResourceMetadataURI is not provided as part of the LearningResourceChoice. LearningResourceChoice now contains a choice between the LearningResourceMetadataURI (as before) and the new LearningResource common type containing the alternate group of properties.

Original ticket description follows:

The choice in EducationContent between specifying the LearningResourceMetadataURI or the learning resource metadata properties does not use a common type for the LRMI elements.

Proposed solution: replace the inline sequence with a new Common type LearningResource which will contain all elements in the current "inline sequence":
