These two seem to be particularly acute for cases of errors in DTD (*cough* SVG 1.1 Basic *cough*) where the parser reports errors at line numbers beyond the number of lines in the actual document. Fixing this with a test on whether the document is actually that long. Also fixing a couple of similar issues in the detection of doctypeless documents.
