Confusing descriptions of lockmeta in DITA 1.2 Spec: CD04, PDF (DITA1.2-spec.pdf)

[Doug Morrison <dmorrison@dita4all.com>]

  In my view, the various descriptions of the lockmeta attribute are 
confusing in DITA 1.2 Spec: CD04, PDF (DITA1.2-spec.pdf).

In Section 3.1.2.1.2 'Metadata in maps and topics' on pdf p38 it says:

quote
By default, metadata in the map supplements or overrides metadata that 
is specified at the topic level, unless the
@lockmeta attribute of the <topicref> element is set to "no".
endquote

In the default situation, what determines whether metadata is 
supplemented or replaced?

I take it that the default is for lockmeta="yes" or lockmeta is absent.

Whatr if lockmeta is present on topicmeta, subjectHead or bookmeta?

I think "<topicref>" should be replaced by "<topicmeta>", because in 
Section 3.1.2.1.2, 'topicref' there is no mention of lockmeta attribute.


In Section 3.1.2.1.3, 'topicmeta' the description of lockmeta is

quote
Indicates whether any of the meta
information should be replaced by meta
information in the referenced topic. If the
value is yes, the information inside
<topicmeta> should not be replaced with
information from the topic.
endquote

Now the sense of the replacement is reversed. The "If" is ambiguous - 
does it mean "If and only if"?
When is metadata supplemented?

Apologies for the lateness of these comments.
