these messages are created when a content stream within a PDF is processed. These streams define the graphical content within a PDF such as text, lines etc.
Now content belonging together can be marked by BMC and BDC to start a kind of group and EMC to end such group. The PDFStreamEngine doesn’t have a special handling for such groups on default as for most use cases such as text extraction or rendering they can be safely ignored. The INFO is simply to inform the user about that.
