This page describes features that are not completed yet or need pratical testing before they're added to the standard feature set. They might disappear or be changed subtantially!
[:page name] and [:page name:link text] are a shorter form of [wiki:Self:...], with the additional benefit that both page name and link text can contain any character, including spaces.
Pro: using spaces, and it allows &#...; recoding (yet to be added) so that it's possible to add non-western chars into wikinames of western/latin1 wikis. This feature is not needed any more as moin-1.3 supports Unicode.
config.default_lang sets the default language of a wiki's content (note: this has not much to do with the user interface language a user sees)
the HTML lang attribute of a page's BODY tag is set to this language
for each language MoinMoin supports in its user interface, a correspondent [[lang]] macro exists, e.g. [[en]]
this macro sets HTML lang attributes for paragraphs etc.
