Has this changed? I read the Style Guide quite thoroughly when I started, and the recommendation at that time was
== Sources ==
<references />
...and underneath, if there were inline references (i.e., <ref> tags), a separate
=== See also ===
...with bullet points underneath to separate it from the numbered references. If there were only bulleted references and no <ref> tags, this See also section could be left out.
As a former professional editor, I have been editing every profile I've touched for the last couple years - amounting to hundreds if not thousands of profiles - to this style standard. If this has changed, I'd like to know.
