<para>This template enables auto-generation of an appropriate
localized "choice" separator (for example, "and" or "or") before
the final item in an inline list (though it could also be useful
for generating choice separators for non-inline lists).</para>
<para>It currently works by evaluating a processing instruction
(PI) of the form &lt;?dbchoice&#xa0;choice="foo"?> :
<itemizedlist>
<listitem>
<simpara>if the value of the <tag>choice</tag>
pseudo-attribute is "and" or "or", returns a localized "and"
or "or"</simpara>
</listitem>
<listitem>
<simpara>otherwise returns the literal value of the
<tag>choice</tag> pseudo-attribute</simpara>
</listitem>
</itemizedlist>
The latter is provided only as a temporary workaround because the
locale files do not currently have translations for the word
<wordasword>or</wordasword>. So if you want to generate a a
logical "or" separator in French (for example), you currently need
to do this:
<literallayout>&lt;?dbchoice choice="ou"?></literallayout>
</para>

<para>The <tag>dbchoice</tag> processing instruction is
an unfortunate hack; support for it may disappear in the future
