New repositories will be added for holding the text changes and the source
What's the case when multiple .MD files are needed?
Specification text changes will be held within the affected source
repository, in the Github flavour of markdown, in a file (or split
across several files) with .md suffix.
(This one may break down where we have a specification change
affecting multiple specifications, but at that point we can track it
with multiple BZ entries)
## Source code
In order to ensure draft code does not accidentally leak into
production use, and to signify when the changeover from draft to final
happens, *all* new or modified identifiers need to be prefixed with the
 Modified in a non-backwards-compatible way. If, for example, a
sized array is grown - this does not need to be prefixed. But a tag in aIf a protocol is enhanced to provide more interfaces with increased revision
comment would be *highly* recommended.
number, would you like the protocol name to be prefixed with BZ####?
Or just the new interfaces added to the protocol are prefixed the BZ####?
I think just prefixing the new interfaces can meet the purpose.
I think pre-fixing the new interfaces is sufficient. Otherwise, you need to modify all code using the existing interfaces (for build verification)
But the protocol definition is changed, it also needs to be prefixed according
to this flow.
Can you clarify a bit more?
A changed protocol definition is not backwards compatible, and typically results in a new protocol GUID. In that case, it really becomes a new definition and need to be pre-fixed per this rule. Right?
If FunctionName or HEADER_MACRO is defined in non-public header files, I
### File names
New public header files need the prefix. I.e. `Bz1234MyNewProtocol.h`
Private header files do not need the prefix.
The tagging must follow the coding style used by each affected codebase.

don't think they require the prefix. Do you agree?
For data structures or enums, any new or non-backwards-compatible |
structs or fields require a prefix. As above, growing an existing
array in an existing struct requires no prefix.
| `typedef SOME_STRUCT` | `BZ1234_SOME_STRUCT` | Typedef only
| `StructField` | `Bz1234StructField` | In existing struct | |
| `typedef SOME_ENUM` | `BZ1234_SOME_ENUM` | Typedef only
 If the struct or enum definition is separate from the typedef in the
header, the definition does not need the prefix.What does "separate" mean?
Does it mean "struct or enum in the public header BzXXX.h don't need the
If yes, then I think macros defined in BzXXX.h also don't need the prefix.
 Individual fields in newly added typedefd struct do not need prefix, theI think only the names (struct type name, enum type name, interface name,
struct already carried the prefix.
Variable prefixes indicating global scope ('g' or 'm') go before the BZ prefix.

public header doesn't have prefix.
The way I read it, *all* new (and non-backward modified) identifiers (typedef struct, typedef enum, and new structfield in existing struct) need to be pre-fixed, regardless if the filename is prefixed or not.
