Which attribute binding is effective?

[Kristen James Eberlein <kris@eberleinconsulting.com>]

So, what is the effective binding for an attribute? First? Last?

Here is a scenario:

Here is the contents of baseScheme.ditamap, which defines the os subject and binds its values to the @platform attribute:

<subjectScheme>
  <subjectdef keys="os" navtitle="Operating system">
    <subjectdef keys="linux" navtitle="Linux">
      <subjectdef keys="redhat" navtitle="RedHat Linux"/>
      <subjectdef keys="suse"   navtitle="SuSE Linux"/>
    </subjectdef>
    <subjectdef keys="mswin" navtitle="Windows"/>
    <subjectdef keys="zos"   navtitle="z/OS"/>
  </subjectdef>
  <enumerationdef>
    <attributedef name="platform"/>
    <subjectdef keyref="os"/>
  </enumerationdef>
</subjectScheme>
 
Another subjectScheme map contains the following content:

<subjectScheme>
  <schemeref href=""/>
  . . .
 <subjectdef keys="app" navtitle="Applications">
      <subjectdef keys="apacheserv" navtitle="Apache Web Server"/>
      <subjectdef keys="mysql"      navtitle="MySQL Database"/>
 </subjectdef>
  . . .
  <enumerationdef>
    <attributedef name="platform"/>
    <subjectdef keyref="app"/>
  </enumerationdef>
</subjectScheme>

Best,
Kris
