Stuff like
<map:resource name="pipe-text-resource">
<map:call resource="generate-transformed-resource">
<map:parameter name="path" value="{path}" />
</map:call>
<map:serialize type="text" mime-type="{mime-type}"/>
</map:resource>
Needs changes since you need to follow close to 5 different resource
declarations to finally found the root of the processing.
Further
<map:match pattern="**.png">
<map:select type="exists">
<map:when test="{lm:project.images.{1}.svg}">
<map:call resource="pipe-aggregate-svg2png-resource">
<map:parameter name="path"
value="{lm:project.images.{1}.svg}" />
</map:call>
</map:when>
<map:when test="{lm:project.images.{1}.aart}">
<map:generate type="asciiart-svg"
src="{lm:project.images.{1}.aart}" />
<map:call resource="transform-project2text"/>
<map:serialize type="svg2png" />
</map:when>
<map:when test="{lm:project.images.{1}.png}">
<map:read src="{lm:project.images.{1}.png}"
mime-type="image/png" />
</map:when>
</map:select>
</map:match>
We are doing here excessive use of the <map:select type="exists"> which
should be done in the lm IMO (but that is hard).
