DDS12 — Naming of filter_parameters concerning ContentFilteredTopic

The method name is get/set_expression_parameters() whereas the parameter passed in is the "filter_parameters". Understandably the full name is filter expression parameters since the ContentFilteredTopic has a "filter_expression" attribute.
Compare this with the MultiTopic which has the same named methods which take in "expression_parameters" and has a "subscription_expression" attribute.
The name "filter_parameters" is also used in the create_contentfilteredtopic() method on the DomainParticipant.

Proposed Resolution:
Change the name of "filter_parameters" to "expression_parameters" for more consistency.

Proposed Revised Text:

Section 2.1.2.2.1 DomainParticipant Class; DomainParticipant class table
On the row describing the operation "create_contentfilteredtopic"
Replace parameter name "filter_ parameters"
With parameter name "expression_ parameters"

Section 2.1.2.2.1.7 create_contentfilteredtopic
Last paragraph replace "filter_ parameters" with "expression_ parameters"

Section 2.1.2.3.3 ContentFilteredTopic Class; ContentFilteredTopic class table
On the row describing the operation "set_expression_parameters"
Replace parameter name "filter_ parameters"
With parameter name "expression_ parameters"

Section 2.1.2.3.3 ContentFilteredTopic Class
On the second bullet towards the end of the section:
Replace "filter_ parameters" with "expression_ parameters"
On the last paragraph just above section 2.1.2.3.3.1:
Replace "filter_ parameters" with "expression_ parameters"

Section 2.1.2.3.3.3 get_expression_parameters
On the first paragraph:
Replace "filter_ parameters" with "expression_ parameters"

Section 2.1.2.3.3.4 set_expression_parameters
On the first paragraph:
Replace "filter_ parameters" with "expression_ parameters"

Section 2.2.3 DCPS PSM : IDL
interface DomainParticipant
On the operation create_contentfilteredtopic
Replace formal parameter name "filter_ parameters" with "expression_ parameters"
