Outgoing links may have a filter set on their source. The filters supported by the broker are:

Filters can be specified through the filter property in the link properties specified in the address. The value of this filter property should be a list of maps, with each map specifying a filter through key-value pairs for name, descriptor (can be specified as numeric or symbolic) and a value. For example:

my-xml-exchange; {link:{filter:{value:"declare variable $colour external; colour='red'",name:x,descriptor:"apache.org:xquery-filter:string"}}}

my-xml-exchange; {link:{filter:{value:"declare variable $colour external; colour='red'",name:x,descriptor:"apache.org:xquery-filter:string"}}}
