Fixed a couple of typos at CC's request in the Sonnet files, and in the process included her short descriptions of the texts, which go into <bibl> elements in the <sourceDesc>. This threw up a new problem. Up to now, these descriptive bits have been one-line plain text items, so the handling code is not expecting anything like titles or italicized text; these new descriptions include text titles that should be italicized. I've had to remove that from the content, until I can rewrite that code. Adding this as a task...
