Indeed, this will do for my purpose (office presentation viewer). But,
as Jerome said, sometimes using style names is more convenient.
Yes but in that case we allow it (as you've shown in your example below) even if not
100% convenient (it's not that bad) :)
I think it's good to direct users to package
more complex things into macros, especially since it's easy to package as a wiki
macro. It has several advantages, one of them being that it makes the "snippet"
reusable.
One issue we have is that wiki macros that import JS/CSS can't be used
inside velocity code. what's the problem?
Nested script macros. We should introduce a:
{{use type="jsx" resource="Space.Page"/}}
to overcome this issue.
