Hello. I just wanted to say that this is a really great XML rules
library. I had already kind of made my own and then decided as
requests were getting more complicated to do research on what else
was out there. I came across this and it's perfect. It also seems to
work in .NET 2.0 very well which is great! I am surprised this is not
talked about more, it was kind of hard to find. Is there any
comparable W3C spec for doing this? What about comparable
applications? Who else makes something like this? It seems rather
unique as its focus is purely on XML. Which is perfect!

Also I had a usage question. I need to replace certain strings in a
node that match a list or otherwise leave them as they are. So I used
calculate to do that like this:

<xr:calculate target="value">
<xr:value when="value = 'A'">'Apple'</xr:value>
<xr:value when="value = 'B'">'Banana'</xr:value>
<xr:value>value</xr:value>
</xr:calculate>

Is this correct? Is there a better way?
