the white soace is coming from, for example
                        >
                        =
                        <
ie the soace you used for indenting. to stop this, use xsl:text so that
                        indentation space is just in text nodes that are
                        all white, thn it will be ignored.


so ...
    <xsl:text> = </xsl:text>

Also, if you are getting
<formatting:ATTRIBUTEVALUE>
"value"
</formatting:ATTRIBUTEVALUE>

then you must have undent="yes" specified on xsl:output, remove this or
set it back to the defualt value of no.
