In CEGUI layout files some properties such as Text and Tooltip can be translated via the localization.csv file through the use of @ tags. For example:

<Property name="TooltipText" value="@MyTooltipTag@" />

At runtime it translates the tag using the global localization.csv file as a lookup dictionary.

There is a function called loc() whcih can be used to grab translations from the mod-local version of localization.csv which resides in the mod folder.

The problem is, you can't call the function loc from inside a CEGUI layout. Only the @tag@ syntax works there. And the @ syntax always uses the global localization dictionary, not the mod-local one.

I want to pull translations from my mod-local dictionary and use them in a CEGUI layout. Is there a syntax using the @ that will allow it?

I noticed that tooltips can have a special tag syntax:
@price[ModNumber].[ClassName]@
which allows the price icons to show up in tooltips on the Main Menu buttons.

Can I use something like:
@[ModNumber].[tagID]@ (e.g. "@10285546.MyTooltipTag@" )
or possibly
@[ModNumber].[tagIndex]@ (e.g. "@10285546.22@" )
to get this to happen?
