I am not sure an XSLT program can easily capture your rules but for the
given sample, if you insert a check on elements whether they both have
attributes and non-whitespace text content and in that case transform
any attributes to sibling following the element, the result is as you
wanted:


<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 B  version="3.0"
 B  xmlns:xs="http://www.w3.org/2001/XMLSchema";

 B  <xsl:param name="namespace"
as="xs:string">http://fc.fasset/product</xsl:param>

 B  <xsl:param name="root" as="xs:string">requestProduct</xsl:param>
 B  <xsl:param name="keepAttr" static="yes" as="xs:string*"
select="'href', 'id'"/>

 B  <xsl:strip-space elements="*"/>
 B  <xsl:output indent="yes"/>

 B  <xsl:template match="/*">
 B B B B B  <xsl:element name="{$root}" namespace="{$namespace}">
 B B B B B B B B B  <xsl:apply-templates select="@* , node()"/>
