Filter section

This section can contain three subsections viz. Enable, Disable & Mappings. All three subsections need not be present in this section but it must at least contain one of the three subsections. Each subsection requires an id of the destination filter. This id can be either naming service identifier or implementation repository identifier (repoid). The filter id is written in another subsection either FilterNS OR FilterRepo based on type of id. Note that allowed subsections are Enable, Disable, Mappings, FilterNS and FilterRepo with no restrictions on their order.
