xml-dev - Re: vcard DTD

[Dave Winer <dave@userland.com>]

>>Dave Winer mentioned a similar issue that forced him to encode some text
in "base64"

If an XML value contains a < or an & you should encode them as &lt; and
&amp;. We researched this and it was there in one of the specs. (Doug Baron
will correct me if I got this wrong). 

The situation I was writing about was truly bizarre. There were two levels
of decoding going on. First I was changing the <s to &lt;s and then they
were being transmitted thru XML-RPC, and on the receiving end the XML-RPC
server thought (as it's supposed to) that it would turn the &lt;s into <s.
Oooops. That was someone else's job (an HTML browser). 

So base64 to the rescue, keep it out of the hands of the pesky server and
get those &lt;s over to the client.
