Non sicuro, se questo è esattamente quello che vuoi/se soddisfa pienamente le tue esigenze, ma sto pensando a ENTITY. Puoi definirli in alto (del tuo documento XML, quindi XML generale, niente di specifico su DocBook). Come visto qui per "doc.release.number" e "doc.release.date". Ma possono anche essere inclusi in un file separato. Come si vede nella terza riga ENTITY. Qui il SISTEMA significa, proveniente da un altro file 'entities.ent'.
<?xml version="1.0" encoding="UTF-8"?>

<!ENTITY doc.release.date "April 2010" >
<!ENTITY % entities SYSTEM "entities.ent" >
%entities;

Nel documento si fa riferimento i soggetti attraverso una partenza &
e termina ;
come in &project.impl.title;
Nel file 'entities.ent' si specificano gli elementi ENTITÀ in modo simile:
<?xml version="1.0" encoding="UTF-8"?>
<!ENTITY project.impl.title 'Maven Tidy Plug-in' >
<!ENTITY project.impl.group-id 'net.sourceforge.docbook-utils.maven-plugin' >
<!ENTITY project.impl.artifact-id 'maven-tidy-plugin' >
<!ENTITY project.impl.release.number '1.0.0.beta-1' >
<!ENTITY project.impl.release.date 'April 2010' >
<!ENTITY project.impl.release.year '2010' >
<!ENTITY project.impl.url '../' >
<!ENTITY project.spec.title '' >
<!ENTITY project.spec.release.number '' >
<!ENTITY project.spec.release.date '' >
<!ENTITY doc.release.year '2010' >
Bello! Quale sarebbe l'equivalente per Docbook v5.0? – jdkoftinoff
