on a related note I do plan to add OTHERWISE support at a DRL level,
just no time to do it right now. Once it's supported at a DRL level,
you won't need to as much work on figuring out the inverse options
etc.<br>

<br>
I'm adding support for "otherwise" to (for the time being) the
guided decision table in Guvnor.<br>
<br>
The idea being if you set a cell to represent "otherwise" the
generated rule is the opposite of the accumulation of the other
cells; perhaps best explained with an example:-<br>
<br>
<div style="margin-left:40px"><span style="font-family:courier new,monospace">Person( name == )</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">Mark</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">Kris</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">Geoffrey</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace"><otherwise></span><br style="font-family:courier new,monospace">
</div>
<br>
This would generate:-<br>
<br>
<span style="font-family:courier new,monospace">Person(name not
in ("Mark", "Kris", "Geoffrey")</span><br style="font-family:courier new,monospace">
<br>
Equals is the simple example, this is my thoughts for the other
operators we might like to support:-<br>
<ul>
<li>!= becomes "in (<list of the other cells' values)"</li>
<li>< becomes ">= the maximum value of the other cells'
values</li>
</ul>
<br>
<div style="margin-left:40px">For example:-<br>
<br>
<span style="font-family:courier new,monospace">Person ( age
< )</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">10</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">20</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">30</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace"><otherwise></span><br style="font-family:courier new,monospace">
<br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">Person ( age
>= 30 )</span></div>
<br>
<ul>
<li><= becomes "> the maximum value of the other cells'
values</li>
<li>> becomes "<= the minimum value of the other cells'
values</li>
<li>>= becomes "< the minimum value of the other cells'
values</li>
<li>"in" becomes "not in (<a list of all values contained in
all the other cells' lists of values>)"</li>
</ul>
<div style="margin-left:40px">For example:-<br>
</div>
<br>
<div style="margin-left:40px">
<span style="font-family:courier new,monospace">Person ( name
in )</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">Jim, Jack</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">Lisa, Jane,
Paul</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace"><otherwise></span><br style="font-family:courier new,monospace">
<br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">Person ( name
not in ("Jim", "Jack", "Lisa", "Jane", "Paul" ) )</span><br>
<br>
</div>
<ul>
<li>I'm not sure there is a simple solution for "matches" and
"soundslike" but welcome advice, although a possibility might
be to create a compound field constraint:-<br>
</li>
</ul>
<div style="margin-left:40px">
<span style="font-family:courier new,monospace">Person ( name
soundslike )</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">Fred</span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">Phil</span><br style="font-family:courier new,monospace">
<br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">not Person (
name soundslike "Fred" || soundslike "Phil" )</span><br style="font-family:courier new,monospace">
</div>
<br>
<br>
Would this be considered the most suitable approach?<br>
<br>
Inputs and thoughts welcome.<br>
<br>
Thanks,<br>
