Ah! The key point. So my courtyard codes are both fancy text and markup.
The fact that they do not enter a markup bubble but instead use individual
code points to convey the formatting information does not alter the fact
that they are markup.

I understand what you mean. However, as regards the second sentence in the
above quote, so as not to seem to agree tosomething with which I am not
agreeing, can I please say that in the dictionary before me at present, the
word proprietary is stated as an adjective meaning "belonging to owner; made
by firm with exclusive rights of manufacture", so I would not wish courtyard
codes to be regarded as a proprietary form of rich text. I fully accept
that you were probably not using the word proprietary to convey that meaning
but to convey a sense that I had made it up myself on my own initiative as
between making it up myself on my own initiative and it being devised by a
standardization body.

Yes. I now understand. Thank you for the explanation.

Well, I did not define codes for long s t ligature and st ligature in the
golden ligatures collection because they are already in regular Unicode.

Thank you for your help.
