Section Number and Name: 
3.1.16.6. cn=index

Describe the issue: 
The section gives the following example:
dn: cn=example presence index,cn=index,cn=tasks,cn=config
objectclass: top
objectclass: extensibleObject
cn: example presence index
nsInstance: userRoot
nsIndexAttribute: "cn:pres" <<<<<<<<<<<<<


The value of the nsIndexAttribute should NOT have double quote.


Suggestions for improvement: 
Please remove the double quote from the example. It should be:
dn: cn=example presence index,cn=index,cn=tasks,cn=config
objectclass: top
objectclass: extensibleObject
cn: example presence index
nsInstance: userRoot
nsIndexAttribute: cn:pres

Additional information: 
 Here is a quick test:

WITHOUT double quote, i.e. nsIndexAttribute: description:eq,pres,sub
