If text has been set via a rich text view, i.e. the text window, the text tag is also stored in RTFD form, even if there is no apparent styling. This example shows a single paragraph of unstyled text "Hello world."
<text >Hello world.</text> <rtfd >cnRmZAAAAAADAAAAAgAAAAcAAABUWFQucnRmAQAAAC7hAAAAKwAAAAEAAADZAAAAe1xydGYxXGFu c2lcYW5zaWNwZzEyNTJcY29jb2FydGYxMzQ3XGNvY29hc3VicnRmNTcwCntcZm9udHRibFxmMFxm bmlsXGZjaGFyc2V0MCBIZWx2ZXRpY2FOZXVlO30Ke1xjb2xvcnRibDtccmVkMjU1XGdyZWVuMjU1 XGJsdWUyNTU7XHJlZDBcZ3JlZW4wXGJsdWUwO30KXHBhcmRcdHgzNjBcc2I4MFxzYTgwXHBhcmRp cm5hdHVyYWwKClxmMFxmczMyIFxjZjIgSGVsbG8gd29ybGQufQEAAAAjAAAAAQAAAAcAAABUWFQu cnRmEAAAAIhdgFW2AQAAAAAAAAAAAAA= </rtfd>
The rtf tag is always deleted if its associated text tag is deleted.
