  # Remove blocks from your cocoon distribution by uncommenting the
  # corresponding exclude property.
  
  # NOTE: Don't modify this file directly but make a copy named
  # 'local.blocks.properties' and modify that. The build system will override
  # these properties with the ones in the 'local.blocks.properties' file.
  
  # NOTE: "[dependency]" indicates blocks that are required by other blocks.
  # Disabling batik, for example, will result in a RuntimeException when using
  # fop. On the other hand some dependencies come only from the block samples.

  # Stable blocks ----------------------------------------------------------------
  
  # Stable blocks are those that can be considered ready for production and
  # will contain components and API that will remain stable and where
  # developers are committed to back compatibility. In short, stuff that you
  # can depend on.
  
  </desc:desc>
  
  <desc:desc name="unstable">
  # Unstable blocks --------------------------------------------------------------
  
  # Unstable blocks are currently under development and do not guarantee that the
  # contracts they expose (API, xml schema, properties, behavior) will remain
  # constant in time. Developers are not committed to back-compatibility just yet.
  # This doesn't necessarily mean the blocks implementation is unstable or
  # the code can't be trusted for production, but use with care and watch
  # its development as things might change over time before they are marked
  # stable.
  
  </desc:desc>
  
  <desc:desc name="deprecated">
  # Deprecated blocks ------------------------------------------------------------
  
  # Although some of these blocks may have been stable, they are now deprecated
  # in favour of other blocks and therefore are excluded by default from the build

      <xsl:message>
  
  There are 2 issues this transformation does not handle at the moment:
  - The order of the @status sections, i.e. stable, unstable, deprecated.
    It depends on the first occurence of a block of one particular section.
  - Default exclude of a specific block. If a block is broken at any time
    and should be excluded, it must be done by hand afterwards.
  So before committing the updated blocks.properties please make a cvs diff
  to see what has really changed.
