John Y recently had to deal with an XML-like dump from a "4D" database. This dump used a peculiar form of abbreviation in which letters were chosen seemingly at random from field names, in order to meet the well known XML limitation of only allowing 5 characters per tag name.
Sometimes less than 5 letters were used. Browsing this file, John encountered the following Zen-like line.
<>There is no phenotype</>
He was enlightened.
