 | This module depends on the following other modules: |
This module exists primarily to provide correct html markup for non–English language text where that text is used in the English Wikipedia. It has a secondary purpose of providing correct visual rendering for this non-English text. The module was developed to consolidate processing for {{Lang}}, the Lua error in Module:Template_link_general at line 144: attempt to concatenate local 'titlePart' (a nil value). (most), and {{Transl}} templates into a single source and to use a clearly defined data set extracted from international standards. It provides error checking and reporting to ensure that the html rendered is correct for browsers and screen readers.
Other templates that get language name support from this module are:
- {{Native name}}
