LaTeX + Biblatex bibliography to other formats via Pandoc

The --biblatex option only applies when the output document is LaTeX format. When I tried pandoc --bibliography=foo.bib -o foo.docx foo.tex it worked for me. If you want Chicago you need to add an option for that e.g. --csl=chicago-author-date.csl. You can get the CSL file from github.com/citation-style-language/styles.
