Problem using SVG serialializer after a transformation

[BORGES Charles <ch...@cegetel.fr>]

Hi,

I run into the following problem when serializing to svg after a xsl
transformation:

Start with a sitemap including something like this
<map:match pattern="*.png">
  <map:generate src="{1}.svg"/>
  <map:transform src="xsl/{1}.xsl" type="xslt"/>
  <map:serialize type="svg2png"/>
</map:match>


Turn the debug on and check for the SVGSerializer logging.
You see that serialization of the xsl transformation output produces the
massage:
"setDocumentLocator was not called, will use http://localhost/ as base URI".

This means that if i have a href in my svg to a css for instance, it won't
be located and the serialization will fail!

I fixed it (somehow) by: 
1.introducing a base-url attribute in the SVGSerializer configuration:
<map:serializer logger="sitemap.serializer.svg2png" 
                  name="svg2png"
                  src="fr.cegetel.dsco.gi.svg.serialization.SVGSerializer"
                  mime-type="image/png"
                  base-url="context://sample/batik"/>
3.using the sourceresolver to find out the uri to set in the document
locator.
2.making the SVGBuilder no more Recyclable.

Be careful: the convention in configurations is that attributes are 
container-related data. Component-related data should be better located 
as child elements. So the following should be better:

<map:serializer ....>
  <base-url>context://sample/batik</base-url>
</map:serializer>

So do you really need the base-url? Isn't the uri of 
SourceResolver.resolveURI("") just what you need? Or at least it can be 
a fallback if base-url is not present.

Why can it no more be Recyclable?
