xmlsectool and prolog

[Ullfig, Roberto Alfredo]

A google search noted that the prolog is optional. I found this:

"The XML prolog is optional. If it exists, it must come first in the document."

I've found several non-federated applications (I don't recall which ones though) which require metadata to be uploaded manually will fail to upload or configure properly if the metadata contains an XML prolog. I've not seen such a problem if the prolog is not there.

That's very curious. Being able to process the prolog is, of course, a mandatory part of the XML specification, so you might suspect that any application that's genuinely having trouble understanding it may have problems elsewhere...


For now, I just made a note for application technicians that the prolog may need to be removed manually from the file before uploading.

Makes sense.
