  Hum, it's possible there is some bugs left there.

  hum, I think this should generate an error. so not OK

  hum, I think this should generate an error. so OK

  hum, right I probably missed the escaping

>  <e a="$x}}"/>        <e a="$x}}"/>      <e a="$x}"/>        __

   same here

>  <e a="{{$x}"/>       <e a="{$x"/>       error               __

   unclear, the first { is escaped, then is } matching necessary ?

>  <e a="{$x}}"/>       <e a="v}"/>        error               __

   I don't see an error here, maybe except the last } might be escaped.

  the best is 1/ to check this sample test with other processor, especially
Saxon 2/ to ask on the xsl-list (it's linked from the error reporting page),
most people aware of the spec can clean this up, and then fill a bug report
because there is certainly some parts libxslt doesn't implement properly.
