Referring to bug 95489 comment 8 from Maxim Monastirsky, any .uno:StyleApply command of built-in styles should get the "internal" non-localizable name when inserting for example as a paragraph style toolbar button in the Customization dialog. Then it should work with all locales without problems. If there is a localized display name for a style command, that name should be used when visible for the user.
That's already the case AFAICS.
