+/**
+ * This class is used to define an album of context.
+ * <p>
+ * A context album is a distributed map of context that will be distributed across all process
+ * instances that require access to it. This class defines the schema (structure) of the items in
+ * the context album, whether the items on the context album are writable or not, and what the scope
+ * of the context album is.
+ * <p>
+ * The structure of items (objects) the context album is defined as a schema, which is understood by
+ * whatever schema implementation is being used for the context album.
+ * <p>
+ * The scope of a context album is a string field, understood by whatever distribution mechanism is
+ * being used for the context album. The distribution mechanism uses the scope of the context album
+ * to decide to which executable entities a given context album is distributed.
+ * <p>
+ * The writable flag on a context album defines whether users of a context album can write to the
+ * context album or just read objects from the context album.
+ * <p>
+ * Validation checks that the album key and the context schema key are not null and that the scope
+ * field is not undefined and matches the regular expression {@link SCOPE_REGEXP}.

+ * This class holds a data schema definition in Apex. A data schema describes the structure of a
+ * single atom of data handled by Apex. This atom of data can be a primitive type such as an integer
+ * or a string, or it can be a more complex data type such as a Java object or an object described
+ * using a data definition language such as Avro. The schema flavour defines the type of schema
+ * being defined and the schema itself defines the schema. The schema flavour is used by Apex to
+ * look up and load a plugin class that understands and interprets the schema definition and can
+ * create instances of classes for the schema.
+ * <p>
+ * An {@link AxContextSchema} is used to define each parameter in Apex events, the messages that
+ * enter, exit, and are passed internally in Apex. In addition, an Apex {@link AxContextAlbum}
+ * instances hold a map of {@link AxContextSchema} instances to represent the context being managed
+ * as an {@link AxContextAlbum}. For example, the state of all cells in a mobile network might be
+ * represented as an {@link AxContextAlbum} with its {@link AxContextSchema} being defined as @code
+ * cell} objects.
+ * <p>
+ * Validation checks that the schema key is not null. It also checks that the schema flavour is
+ * defined and matches the regular expression {@link SCHEMA_FLAVOUR_REGEXP}. Finally, validation
+ * checks that the defined schema is not a blank or empty string.
