loadComponentFromURL Document Type Detection Failure

[dCipher]

Hi

I have been using the loadComponentFromURL for years with automation but
recently it has given errors saying that the documentation type detection
failed. So I wondered if there is a property I could set that indicates the
document type. I have found a list of document types for SCalc but cannot
find a complete list of document type names supported by Libre Office. Is
there such a list and where can I find it? Secondly would LibreOffice use
the such a property in opening a document instead of relying on document
type detection?

Thanks
Simon
