how to get multi-line author in ODT export?

[Eric S Fraga]

Hello all,

I am trying to generate a multi-line author for a report exported to
ODT.  In LaTeX, I would simply put \\ between lines in a single
#+author: entry, i.e. using @@latex:\\@@ in org.

In normal text, a \\ translates to <text:line-break/> in the ODT export
but this doesn't work in an ODT sub-title entry, for some reason.  This
is somewhat beyond my odt-foo unfortunately.

Can anybody help?

Thank you,
eric

PS -I still do not understand why we cannot use \\ in an AUTHOR field
when it is fine in text...  but I'm sure there's a reasonable
explanation so no worries. :-)
