[Po4a-devel] a small question about translation

[hottea]

hi,
I'm trying to translation po4a to Simplified Chinese, and there is a 
small question when I do the work. I could not get the meaning of this 
sentence:

The po4a (PO for anything) project goal is to ease translations (and 
more interestingly, the maintenance of translations) using gettext tools 
on areas where they were not expected like documentation.

What does "where they were not expected like documentation" ? Does it 
mean gettext tools are not good at documentation translation? I don't 
usually meet this, so I'm so familiar with it.
