I can't see what you mean. Tell me what happens.

It does. Russians don't normally transliterate letters and it's hard
to read transliteration though a standard exists. Russian is currently
written in Cyrillic script only, changing it to Arabic or Lating would
change the language.

That's what the xml:lang="" is for. Markup your CSS examples with

<code xml:lang="">tr { vertical-align: top; }</code>

(because CSS is not a human language)

and a smart spell-checker will skip the block.

A matter of taste and perhaps linguistic knowledgde. If you consider
fiancÚ or na´ve an English word (I do, as they're in dictionaries)
then mark them up as English.

Mark them up accordingly. If I had to write the word "web-page" in
Russian I would type (transliterated):

<span xml:lang="en">web</span>-stranitsa.

This is currently solved by extracting all the
content-that-might-be-visible from the attributes.
See http://www.w3.org/TR/xhtml2 for details.
Normally, I would expect the attributes to have the same language
with the element. It's written somewhere in the specs btw.

That is a problem. The W3C fellows who are responsible for markup
could easily figure out the origin of the people's names that are in
the spec but they don't do that for some reason. Masayasu Ishikawa or
Martin Duerst and even Marja-Riita Koivunen cannot be pronounced
appropriately (and therefore transliterated, e.g., into Russian)
without the markup.
