xyzCodeMark prevents the xyzCode end pattern from matching. This allows
nesting of syntax regions. You can use the "keepend" keyword on the xyzCode
region, but this will disable nesting of that region unless you also use
"extend" where needed.
The better method for this specific case is to use "matchgroup" instead of
creating contained matches for the start and end patterns. :help
:syn-matchgroup.
