After much massaging with XSLT, the 1800s data XML file, which began as a raw RTF document and was transformed to an almost-well-formed XML file by SA, is almost error-free and ready to go to the proofer. In approximately 41,200 lines of data, there are 116 validation errors, which will need to be corrected manually by SD or his proofer. I tried to cover all of the irregularities when writing the XSLT stylesheet, but these remaining errors need to be fixed by someone with the raw data in hand.
