Re: [xsl] adding variables

Hi Bryan,

there are many different possible solutions.

This can be shortened to <xsl:variable name="y_offset" select="20"/>

1. very close to the solution: <path d="M 35, {$y_offset + 25} ..."/>

2. That's not quite correct:

<path>
    <xsl:attribute name="d">
        <xsl:text>M 35,</xsl:text>
        <xsl:value-of select="$y_offset + 25"/>
        ...
    </xsl:attribute>
</path>

But I would prefer the first method using attribute value template.

3. And a complete different solution using SVG: You must group all elements
with the $y_offset and translate() them:

<g transform="translate(0 {$y_offset})">
    <path d="M35,25 ..."/>
</g>

Maybe this is the cleanest and easiest solution.
