As for readability, I would prefer

B  select="case"

to

B  B select="child::case"

but I am pretty sure others have different preferences.


The

group-by="matches(upper-case(substring(normalize-space(caseName/.), 1,
1)),'^[A-Z]')"

seems to use substring to select the first character after white space
normalization, then in the regular expression ^ to match from the start,
it seems

B B group-by="matches(normalize-space(caseName), '^[a-z]', 'i')"

would do the same, i.e. check that the first character in caseName after
white space normalization is an ASCII letter.

But again, the shorter expression might appear easier to read by an
outsider while the longer expression might just express how you thought
about selecting the value for the group by.
