Description:
The message you get when executing fo:fo and navigation.xml is missing is excessively cryptic. 
    [echo] Generating C:\extant\work\portalizer/target/docs/project.fo ...
    [java]
    [java] (Location of error unknown)XSLT Error (javax.xml.transform.TransformerException): java.net.UnknownHostException: C

The reason is because the URL expands to:
file://C:/path/to/maven/xdocs/navigation.xml
This is interpreted as having a host of 'C'. This is partly a xalan issue, but since maven knows it is using a file: url, the message can be improved.

eg, in plugin.jelly,
    <available file="${maven.docs.src}/navigation.xml" 
      property="maven.fo.navigation.available"/>
    <fail message="Cannot find ${maven.docs.src}/navigation.xml"
      property="maven.fo.navigation.available"/>
    <java classname="org.apache.xalan.xslt.Process" fork="yes">
    [...etc...]

fails with the much more informative message:
[ERROR] BUILD FAILED
[ERROR] Cannot find C:\extant\work\portalizer/xdocs/navigation.xml
