[XeTeX] newcommand with optional arguments

[Diederick C. Niehorster]

Thanks, that did the trick.

I'm moving on now with the possessive cite command to automatically include
the correct possessive suffix, `'' for strings ending in `s', `'s' in other
cases.
This proves difficult, probably as I have never attempted to write a tex
macro before. Please find attached what I have got so far.

Now, I have two problems:
- The \posssuff{\citeauthor{#2}} on line 47 does not return the correct
suffix. This is because right now the macros simply operate on the citation
key, not on the actual author-string as will appear in the pdf.
I do not know how to query this author-string given the citation key and
then operate on it.
- The \posssuff macro doesn't work. It is supposed to test if the last
character of the input is an `s' and print different stuff based on that.
However, it seems that currently the else branch is always executed, even if
the \if should be true.

For the second problem, what am I doing wrong?
For the first; is this possible and can someone point me in the right
direction?

Any comments on the macros in general are also appreciated of course!

Thanks for your help,
Diederick
