Hi Richard,

May be all what to say have already been said. Nevertheless I would like 
to give my feedback.

I think a good bidi-phrase would be
   "w3c ... IN 7 POINTS"
to be rendered in Arabic in RTL
   "STNIOP 7 NI ... w3c".
It's a good phrase because it also contains punctiation between RTL and LTR.

--- The problem ---
I've already experienced the problem with this phrase as a title in the 
arabic version of W3C in 7 points "http://www.w3c.org.ma/7points/".
After some tests I found that the title element (as well as title/alt 
attribute) are treated in LTR.
Adding dir="rtl" in the title element seems to have no effect.
I thought of a browsers bug.

Browsers have little differences when rendering this phrase. Moreover, 
some of them make difference between title element and title attribute.
Windowing system may also have a role. For example, in some situation, 
Mozilla15 for MacOSX put its logo "Mozilla" juste between "w3c" and 
"STNIOP 7 NI ...". It seems like if mozilla has concatenated its logo 
with "w3c" before displaying the Arabic part of the title!

--- The solution---
I found two solutions:
1- Type "manually" the phrase in a "RTL" ordering:
    "IN 7 POINTS ... w3c"
2- Use the pair of unicode control characters  RLE/PDF (&#x202B; 
&#x202C;) to force the titles to RTL mode.
I lean to 2.

I've put some examples in http://www.w3c.org.ma/Tests/bidiTitle/
