The rules about tag sequences

[William_J_G Overington]

In seeking to draft a reply to the comments in the

https://www.unicode.org/L2/L2021/21099-qid-feedback.pdf

document, I have wondered about the following questions.

Can we discuss them please?

Is it within the rules for tag sequences to have as a base a sequence of 
a character followed by one or more combining characters before the 
sequence of tag characters starts? The idea being that the particular 
base character followed by one or more combining characters sequence is 
chosen is one very unlikely to be used otherwise, thus avoiding 
confusion.

Can any entity, whether a company or an individual, publish a tag 
sequence and it be valid, or does it need approval by the Unicode 
Technical Committee?
