XML in Bilingual language

@harishkumar As per VAT Regulations, Tax Invoices must be in Arabic language (text that is visible on human readable form of invoice). To provide Arabic and English you can provide the values in same field and use a | separator (please look at sample XMLs in SDK). Content on human readable form of invoice cannot be different from content in XML. If XML has both Arabic and English content then same must be visualized on human readable form.
