Replacement for boolean !?

> Hi,
> I have a need to use something like a boolean. I tried several things but I am running out of ideas to handle something like this in XSLT. I have several blocks of code in my stylesheet. Basically, what I need to do is set a boolean variable to true if some condition is satisfied and act accordingly, SEVERAL BLOCKS down. So, something like this does not seem to be an option:
> 	<xsl:variable>
> 		<xsl:choose>
> 			<xsl:when test="...">
> 			</xsl:when>
> 			<xsl:otherwise>
> 			...
> 			</xsl:otherwise>
> 		</xsl:choose>
> 	</xsl:variable>
> 
> Could anyone please give me an example as to how I could use boolean variables. This is what I need.
> 
> 1. Set boolean to false, initially.
> 2. Open FOR loop.
> 3. Check condition. If true, set boolean to true.
> 4. If boolean is true, do something.
> 5. set boolean to false.
> 6. close loop.
> 		
> Please advise.
