XSL:IMPORT

I have a question regarding the following design


XSL file(a.xsl) which has few xsl:variable declarations
                       ||  
	           V  Imported into

XSL file(b.xsl) which uses xsl:import to import a.xsl and refers both a.xsl
variables and XML file's elements
		^
		||
 XML file with some elements which has b.xsl as stylesheet

1) Will xsl:import work in IE5?.If it works,will xsl:value-of select="$var1"
work to access the variable declared in a.xsl?
2) If IE5 does not support xsl:import,is there a way I can do this design?


Any help is appreciated.
