	63	+== Local variables ==
43	43
	65	+Local variable is a type of variable that can be newly created and used for a certain need.
44	44
	67	+So as to create a local variable "newVar" with a value equals to "var number 1", we should write this piece of XSL code :
	68	+
	69	+{{code language="XML"}}
	70	+<xsl:value-of select=" ixf:SetVar('newVar', 'var Number 1')"></xsl:value-of>
	71	+
	72	+{{/code}}
	73	+
	74	+The call of this new variable in the scnario is similar to previous system variables:  **${newVar}.**
	75	+
	76	+To get 'newVar' from XSL file :
	77	+
	78	+{{code language="XML"}}
	79	+<xsl:value-of select="ixf:getVar('Var')"></xsl:value-of>
	80	+{{/code}}
