anchor.diff:  Use these attributes to refer to documentation for the related subproject, e.g.
   
   [source,adoc]
  -xref:{camel-version}@camel:eips:enterprise-integration-patterns.adoc[]
  +----
  +# use lowercase xref!
  +XREF:{camel-version}@camel:eips:enterprise-integration-patterns.adoc[]
  +----
   
   If there's a missing attribute, raise an issue rather than using a concrete version.
positive.code: To assure this happens without maintenance issues, leave out the version and component segments from the xref, e.g. in the `components` component
  
  [source,adoc]
  xref:eips:enterprise-integration-patterns.adoc[]
  
  NOT
  
  [source,adoc]
  xref:next@components:eips:enterprise-integration-patterns.adoc[]
  
  Do this no matter how many locations the component is distributed over.
  
  
negative.code: For example, this will link to this page from anywhere in the documentation:
  
  [source,adoc]
  ----
  # use lowercase xref!
  XREF:user-manual::improving-the-documentation.adoc[]
  ----
  
  === Links between subprojects
