Here's a transformation that expands the single "style" attribute into the
components that you want.  I won't claim that it's the best way to do it, 
or even an efficient method, but it works.  (Tested using Xalan-J 2.4.1
on a Linux box.)
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:output method="xml" indent="yes" />

	This template adapted from the one on page 435 of
	the book XSLT, by Doug Tidwell, published by
	O'Reilly & Associates
<xsl:template match="*">
	<xsl:element name="{name()}">
		<xsl:for-each select="@*">
			<xsl:when test="name()='style'">
				<xsl:call-template name="expand-style">
					<xsl:with-param name="stylestr" select="."/>
				<xsl:attribute name="{name()}"><xsl:value-of
		<xsl:apply-templates select="*|text()"/>

	Here's the template that splits the style into
	separate attributes and values.  It uses the
	normalize-space( ) function to get rid of any extra
	blanks around the : and ; in the style attribute.

<xsl:template name="expand-style">
	<xsl:param name="stylestr"/>
	<xsl:if test="contains($stylestr,';') or 
		normalize-space($stylestr) !=''">
		<xsl:variable name="attrValPair" select="substring-before($stylestr,';')"/>
		<xsl:variable name="attr"
		<xsl:variable name="value"
		<xsl:attribute name="{$attr}"><xsl:value-of
		<xsl:call-template name="expand-style">
			<xsl:with-param name="stylestr"
