I'd stared repeatedly at
<parser-exclude class="org.apache.tika.parser.ocr.TesseractOCRParser"/>
in the docs. seemed reasonable that since TesseractOCRParser *is* the default
parser, exlcuding it made no sense.
guess not!

<?xml version="1.0" encoding="UTF-8"?>
<properties>
<parsers>
+ <parser class="org.apache.tika.parser.DefaultParser">
