Do we need to introduce new special element - <map:global-parameters/> -
here? Won't it be better to just declare parameters right inside
<map:pipelines/> element?

Then it will be simply:

<map:pipelines>
  <map:parameter name="skin" value="forrest-skin"/>

(Which can be thought of as: "parameters for the *all* pipelines)

  <map:pipeline>
    <map:match pattern="test">
       ...
       <map:transform src="{../skin}.xsl"/>
    </map:match>
    ...

</map:pipelines>
