The figures you described are advanced variations. They can be "modified version" of syllabus figures (figures danced in advanced ways, like Slow Lock, Standing Spin), can be ballroom line (to make dances more beautiful and attractive, like Lunge, Hinge Line, Chair), can be advanced figures (not listed in ISTD books, like Ronde action).

When managed all figures in ISTD technique books, you then have basic conditions to learn advanced technique and figures. As you see in competitions, couples don't dance syllabus figures (ISTD books) much, but they uses their technique to danced competition figures. So, basic figures in ISTD books are so important to achieve a very high level in dancing.

Telemark and Weave, as my opinion, can't be brought in Gloss of Terms since they can be danced in various way in 4 standard dances. They are figures, not technique, so is not a good idea to write a book to describe figues beside ones of ISTD.

As far as I know, the dance called "bebob" in Vietnam was born to dance along the rhythm of Disco and Pop, very popular in 1980s-1990s. No country else have this dance. There is also a music style named "Bepop", but that is not the case here.
