is it comforming beahviour?

[Andrei Smirnov <as...@hotjobs.com>]

is output of transformation (included at the bottom) conforming to spec?

result is:

<?xml version="1.0" encoding="UTF-8"?>
<root>
<el/>
</root>

i.e. atrribute with empty value is striped off.
strange thing is if attribute has content (space is used here) it 
shows up:

<?xml version="1.0" encoding="UTF-8"?>
<root>
<el atrr=" "/>
</root>
