While HTML and other application conventions solve the language tagging
problem in particular domains, they do not do so in a way that satisfies
this requirement in plain text domains. The proposed mechanism does not
conflict with the HTML mechanism; indeed, the HTML mechanism would be
preferred in that context. Note that a similar issue arises with respect
to bidirectional overrides and embedding levels. 10646 encodes these
directly as their absence would preclude minimum legibility of many bidi
texts in the plain text context. However, when using a richer representation,
like HTML, these should generally be replaced with markup at the higher
level. Langauge information can be handled similarly.
