No autocompletion on xsi:nil values

[fbricon]

Given the following snippet:

<?xml version="1.0" ?>
<foo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <bar xsi:nil="">Fred</bar> 
</foo>

There's no autocompletion for xsi:nil values. I expect to see true and false

[fbricon]

true/false combo only shows right after autocompleting xsi:nil. Doesn't work in the example above
