Please do not forget the \startquotation\stopquotation.

I am citing the APA rules, not stating anything on how ConTeXt (or
TeX-Edit or anything else) sorts lists in general.

Brown precedes Browning because APA sorts on last names.
Singh precedes Singh Siddhu because "nothing precedes
something"( Siddhu)
López precedes López de Molina for precisely the same reason.
Ibn Abdulaziz precedes Ibn Nidal because Ibn is not to be taken into
Laue, M. von precedes Röntgen, W. C, as well as Van der Waals, J. D. but
here things start to get tricky!

My point is that sorting lists of course depends on what you are
listing. Indexing author names, for example, needs to sort on last
names, then first names. Indexing on several levels needs to sort first
by the first level, then by the second level, ...

When indexing items containing several words, the sorting should go
word by word, thus
tipografía digital

This amounts to making whitespace higher precedence than anything else,
which I believe was not the case but now is fixed.
