7. Relation of Items and CRs
1.1 type parameterization of types  open
1.5 passing omit to value parameters  resolved in v3.3.1
2.1 Identifying library-internal functions and data  open
3.4 Parallel execution of test cases  CR from 2006
5.1 Real-time semantics  open
5.2 Timing constraints  open
6.3 Hex representation for integers  won’t fix
6.4 Macro definitions  won’t fix
6.5 Time-constraint send operations  won’t fix
6.6 Some new predefined functions (record/set of manipulation)  resolved in v3.3.1
all others are covered by CRs

8. 3GPP CRs
2148 ASN.1 keyword DEFAULT  resolved in v3.3.1
416 Passing omit to value formal parameters  resolved in v3.3.1
2147 implicit omit for coding  proposal prepared
2150 encoding/decoding functions  proposal prepared
2151 local timer  proposal prepared – semantics change – decision needed!
2152 constants  proposal prepared
2144 TTCN-3 reserved words used in other languages  done for ASN.1 (!) and IDL, awaiting the XSD document
2027 ASN.1 (2007) to TTCN-3 mapping  ongoing work
Proposal: definition of a part1 mockup v as v4.1.1 publication may be too late for 3GPP
Needs support from tool vendors

9. Work Plan
Address the mandatory items of the ToR and prepare input for the optional ones
Depending on new incoming CRs we may not resolve all planned CRs
CRs received after writing ToR for current STF: 51 (!) new CRs
23 of the new CRs have been resolved in v are resolved for v (!) new CRs are open for v4.1.1
