Summary0029256: Application Framework - TDocStd_Application does not provide an interface for appending entities to already opened document
DescriptionTDocStd_Application provides only method TDocStd_Application::Open() for opening existing files, which basically creates a new document.

This is inconsistent with other XDE interfaces STEPCAFControl_Reader::Transfer() / IGESCAFControl_Reader::Transfer(), which appends new roots to existing document.

In general, either the reading part should be improved to provide a new mode or auxiliary tool which would allow merging one document into another.
TagsNo tags attached.

It seems TDF_CopyTool/TDocStd_XLinkTool are too low-level tools for such operations - I have no like guessing how to use them for appending content of one opened document to another one and have got corrupted result / crashes due to NULL-dereference afterwards.

Could you provide an example of crashing code allowing to reproduce the problem?
