Is there the way to use "Highlight File Format" with Acrobat Reader 9.0 or later?

Question

hi
Do anyone know the way to use "Highlight File Format" with Acrobat Reader 9.0 later or substitutional way to highlight a PDF file as well as highlight file?
I want to highlight some words by indicating character's location(from n to m) using Acrobat Reader 6, 7, 8, and 9.
I use highlight xml file to highlight words in Acrobat 6, 7, and 8.
http://www.adobe.com/devnet/pdf/pdfs/HighlightFileFormat.pdf
According to this documents, "External Window Handler Plugin" is required to use highlight file.
But I cannot find this plugin in Acrobat Reader 9.
So Acrobat Reader doesn't recognize highlight file.
Well, I know that there is another way to highlight pdf file. It is called "PDF Open Parameters".
However this parameters cannot indicate location of characters but words which is to be searched.
This parameter does not work perfectly to substitute a highlight xml file.
To satisfy what i want to do, the best solution is that Acrobat Reader 9.0 recognizes highlight xml file.
But I think it is impossible because of lack of plugin.
Do anyone know the way to recognize a highlight xml file to 9.0 or another way to highlight some words?
thanks,

The feature is disabled by default in reader 9
(1) Open Adobe Reader
(2) Click Edit > Preferences > Search, and
(3) check the box labelled Enable search highlights from external highlight server.

I can't imagine why Adobe choose to disable it. It's a bad joke for us at UNESCO (http://unesdoc.unesco.org)
