Catalog entry for custom filtering

Any new custom-filtering implementation must be registered with the cpnz:dita:custom:xsl:filter.xsl catalog entry. If you want to implement a new custom-filtering, make sure to let a catalog entry point to your filtering stylesheet.

Here is an example of a catalog entry for the custom filter stylexsheet. The filtering stylesheet in this example is named component-filter.xsl.
<group xml:base="xsl/">
  <uri name="cpnz:dita:custom:xsl:filter.xsl" uri="component-filter.xsl" />
