RE: XSL:Number, value attribute

<list seed="3" format="1.a">
<item>item 1</item>
<item>item 2
<list seed="2">
<item>sub item 1</item>
<item>sub item 2</item>
</list>
</item>
<item>item 3</item>
</list>

3. item 1
4. item 2
 4.b. sub item 1
 4.c. sub item 2
5. item 3

Using the "value" attribute of xsl:number gives you access to the number
formatting functionality of xsl:number without the node-counting
functionality. For example

<xsl:number value="7" format="i"/>

gives you "vii", regardless of where the context node is in the source
tree. This means that value can't be used with multi-level numbering (at
least in XSLT 1.0 - in 2.0 the value attribute can be a sequence of
numbers).
