[sca-c-cpp] NEW ISSUE: Requirements on cpp:parameter/@type too lax

["David Haney" <haney@roguewave.com>]

Target: C++ C&I Specification CD03

 

Description:

The requirements on the cpp:parameter/@type attribute (Section D.6) are too lax, and allow specifying any valid C++ type.  There isn’t enough information to support conversion to/from any arbitrary type.

 

Proposal:

 

Restrict the allowed types to those explicitly identified in the spec:

 

·         type : Name (0..1) – specifies the type of the parameter or struct member or return type.  The @type attribute of a <cpp:parameter/> element MUST be a C++ type specified in section 10.3.1.

 

Rationale:

 

• Since std::string is a valid type from section 10.3.1, the type of this attribute cannot be NCName.  Switched to Name.
• Since the default mapping is taken from this table, it seems to be a reasonable subset to choose the mapping from.
