For the {{lang-xx}} templates, the only parameter required to be set in the template is the language code. All
other parameters can, usually should, be written in the template call. For {{lang-xx}} templates for languages
that can have multiple writing systems, it may be appropriate to set |script= as well.
For each {{lang-xx}} template choose the appropriate entry-point function so that this function knows the default
styling that should be applied to text.
For normal, upright style:
<includeonly>{{#invoke:lang|lang_xx_inherit|code=xx}}</includeonly>
For italic style:
<includeonly>{{#invoke:lang|lang_xx_italic|code=xx}}</includeonly>
All other parameters should be received from the template's frame (parent frame)
Supported parameters are:
|code = (required) the IANA language code
|script = IANA script code; especially for use with languages that use multiple writing systems
|region = IANA region code
|variant = IANA variant code
|text = (required) the displayed text in language specified by code
|link = boolean false ('no') does not link code-spcified language name to associated language article
|rtl = boolean true ('yes') identifies the language specified by code as a right-to-left language
|nocat = boolean true ('yes') inhibits normal categorization; error categories are not affected
|cat = boolian false ('no') opposite form of |nocat=
|italic = boolean true ('yes') renders displayed text in italic font; boolean false ('no') renders displayed text in normal font; not set renders according to initial_style_state
|lit = text that is a literal translation of text
|label = 'none' to suppress all labeling (language name, 'translit.', 'lit.')
any other text replaces language-name label - automatic wikilinking disabled
for those {{lang-xx}} templates that support transliteration (those templates where |text= is not entirely latn script):
|translit = text that is a transliteration of text
|translit-std = the standard that applies to the transliteration
|translit-script = ISO 15924 script name; falls back to code
For {{lang-xx}}, the positional parameters are:
{{{1}}} text
{{{2}}} transliterated text
{{{3}}} literal translation text
no other positional parameters are allowed
