 CP

CP is used with verbs like "say", which can be used in a quotation or paraphrase: 

     +-------------------CP---------------------+
     |                        +-------Xd--------+
     |                        |         +---S---+-Xc-+
     |                        |         |       |    |
  ///// The President is busy , the spokesman said /////
Verbs that can take quotational complements of this kind have "CP-", directly disjoined with their other complement connectors. The verb must connect to commas on either side (or to the right- hand wall); see "Xc". Direct quotations, with quotation marks, use the QU connector to explicitly locate the quoted phrase or sentence. 
  say: (S- or I-...) & (O+ or Ce+ or TH+ or (Xd- & Xc+ & CP-));
Verbs that can be used this way can usually also be placed elsewhere in the sentence - either after an opener (ex. 1), or after the subject phrase (ex. 2). In the first case, they use COq; in the second case, they use Eq. 

                +-------------S---------------+
                |                       +-Eq--+
                |                       |     |
1.	The President , the spokesman said , is busy

        +---------------------CO--------------------+
        |                              +-----COq----+
        |                              |            |
2.	At the moment , the spokesman said , the President is busy
Verbs such as "say" therefore have the following: 
	(S- or I-) & (O+ ... or (Xd- & Xc+ & (CP- or Eq+ or COq-)));
The category of verbs that can take quotations like this cuts across other verb categories. For that reason, it seemed simpler to designate new dictionary entries for quotation-taking verbs; these entries have only the complement connectors used in quotation (CP, Eq, and COq). Such entries are subscripted with ".q" ("say.q", etc.).

Quotation complement connectors - CP, Eq, and COq - are all domain-starting. The structures created in such sentences are rather unusual, however. With domains, the usual principle is to have embedded clauses nested inside the domains of main clauses. In cases of quotation, it would seem (semantically anyway) that the quoting verb (e.g. "say") is the main clause, and the quotation itself is dependent on it. Therefore, we make the quoting expression start a domain which includes the quoted expression. In the case of Eq, and COq, these links are simply made domain-starting links. In the case of CP, the "Wd" connector on the wall already starts a domain which only includes the quoted statement. CP is then made to start an "urfl" domain (of type 'd'), which includes both the quoted statement and the quoting statement. 

     +-------------------CP(d)------------------+
     |                        +-------Xd(d)-----+
     +-S(d(m))-+              |         +--S(d)-+Xc(d)+
     |         |              |         |       |     |
  /////	The President is busy , the spokesman said  /////

CPi: Filler-it paraphrasing

CPi is used with verbs taking paraphrase statements which also require "filler-it" as subject: "The President is busy, it seems". See "SF: filler-it".

CPu: Thoughts and desires

CPu is used with verbs that express beliefs, hopes, thoughts, desires, knowledge, assertions, etc. It interacts heavily with the VCz link, as well with the head-verb connectors WV and CV to identify the verbs in the sentence, together with their roles. 
      +------------------------->CPu------------------------->+
      +--------->WV------->+                                  |
      +----->Wd-----+      +------VCz-----+---------CV------->+
      |      +--Ds--+--Ss--+--Pa--+    +Xd+-Sa*a+--I---+--Pv--+
      |      |      |      |      |    |  |     |      |      |
  LEFT-WALL the  accused   is innocent ,  as  shall    be   proven
This verb class generally includes the mental-state and mental-act verbs, and some passive performative verbs ("the accused is innocent, as recognized by this court").

CPa, CPx: Topic-less paraphrasing

CPa and CPx is used for paraphrasing-like constructions in which the paraphrased content (the topic) is absent. CPx is used for direct assertions: 
       +-------->CPx--------+
       +->Wa--+     +---Ss--+-Xp-+
       |      |     |       |    |
   LEFT-WALL so everyone   says  .
CPa is used for inverted subjects: 
      +---->CPa----+------Xc------+
      |      +--Em-+--SIsj--+     |
      |      |     |        |     |
  LEFT-WALL so   thinks everyone  .
