Description
referenceIds
[out] Receives the BlockReference Object ID's.
directOnly
[in] If true, returns only direct references.
forceValidity

Remarks
If this Block is nested, references to the parent block(s) will be included if and only if directOnly is false. Older drawings do not explicitly store this information, and hence must be completely loaded.
