Unset variables

Is there any element to unset an environment variable in the XML 
profiles? or should it be done with <execute>:

<execute command="unset">

Another question: Are pipes and stream redirections accepted within the 
<param> elements of <execute>? Take the following as example:

<execute command="ls">
	<param>-l | sort >> /tmp/ls.txt</param>

Thanks in advance for any help.
