Why not "abdg" for the second entry?

For the first entry (phrase indexing), don't we need to define a new 
element instead of index_subfields (something like 
index_subfields_as_phrase)?
like:
<index_subfields_as_phrase 
xmlns="http://www.koha-community.org/schemas/index-defs" tag="700" 
subfields="abdg">
or maybe to use an attribute like "index_as_phrase" so that the new xsl 
template could be applied only if we want so?
like;
<index_subfields 
xmlns="http://www.koha-community.org/schemas/index-defs" tag="700" 
subfields="abdg" index_as_phrase="yes">
Are we allowed to use new elements or attributes in *-koha-*.xml files ? 
There is a namespace defined in the file : 
xmlns:kohaidx="http://www.koha-community.org/schemas/index-defs". But I 
cannot find the definitions either on koha-community.org, or elsewhere. 
Do you know if it is avaiable somewhere?

Excuse me if my remarks are silly, I don't really know XSLT ;-)
