    Set generate.consistent.ids in xsl stylesheets for more repeatable builds
    
    Causes auto-generation of id attributes to use values based on position in
    document, such as id="id-1.5.9.5.2", instead of based on memory address of
    parse tree, such as id="idm140664351287904", so that generated documents
    end up with the same contents across rebuilds & platforms (especially on
    platforms using address space layout randomization).
    
    Does not guarantee long-term stability of links across releases, just
    repeatability when building the same release multiple times - values
    will change when documents are edited to add/remove/reorder sections.
    
    Only effective when used with version 1.77 or later of the
    DocBook XSL stylesheets (released in 2012).
