Re: [dita] How much flexibility do specializers have to make exceptions to behaviors that are outlined in the DITA standard?

3.       For specializations the "processing behaviors" described in the DITA specifications are not required, but are strongly encouraged default behaviors unless explicitly stated otherwise. Here “strongly encouraged” means that there may be valid reasons in particular circumstances to implement exceptions to the described default behavior, but the full implications of such exceptions must be understood and carefully weighed before choosing to implement behaviors that differ from the default behaviors described in the DITA specifications.
