[Exist-open] Indexing on namespaced attributes (eXist 2.2)

[Jo C. <jo....@m-...>]

Hi all,

It does not seem possible to use an index specification such as:

     <index xmlns:gml="http://www.opengis.net/gml/3.2" 
xmlns:xlink="http://www.w3.org/1999/xlink">
         <range>
             <create qname="@xlink:href" type="xs:string"/>
             <create qname="@gml:id" type="xs:string"/>
             <create qname="gml:identifier" type="xs:string"/>
         </range>
     </index>

Looking at the indexes via monex, the "gml:identifier" index looks to be 
functioning perfectly.  Either of the other two gives rise to the 
following exception:

err:XPTY0004 checking function parameter 2 in call util:log("DEBUG", concat("INDEXES qname     :    ", $indexes:qname)): Invalid lexical form of either prefix or local name. [at line 207, column 70, source: /db/apps/monex/modules/indexes.xqm]
In function:
	indexes:show-index-keys(node(), map) [32:9:/db/apps/monex/modules/indexes.xqm]
	templates:call-with-args(function, function*, element(), map) [208:13:/home/exist/eXist-db/webapp/WEB-INF/data/expathrepo/shared-0.4.0/content/templates.xql]
	templates:process-output(element(), map, item()*, element()) [205:9:/home/exist/eXist-db/webapp/WEB-INF/data/expathrepo/shared-0.4.0/content/templates.xql]
         ...

Commenting out the log call in the module appears to lead to later 
failures, and null output from the page.

Query performance suggests that the relevant indices are not created.

Obviously, building a document which removes the namespacing is a 
possible, but quite costly, workaround.  So, have I missed something 
obvious?

Install details are:

eXist Version: 	2.2
eXist Build: 	20141120
Operating System: 	Linux 4.4.0-64-generic amd64
