C2: esql:if-null

["Mark S. Kent" <ma...@vistyx.com>]

<esql:if-null column="colname">

Has anyone used this yet?  What is the exact syntax for the esql statement?
The ESQL Taglib page is rather sparse explaining it and the only message in
the archives was suggestions on how to implement it.

I have a Location name/nbr string that I want to create like this:
	"{LocationName} #{LocationNumber}"
but sometimes the number is "null" so I want to just see this instead:
	"{LocationName}"

TIA!
Mark
