A while ago, I needed the opposite of InvRegistry.RegisterInterface(TypeInfo(MySoapInterfacePortType, 'urn:myURN', 'utf-8');, so instead of registering an interface with a namespace URN, obtain the URN by passing the interface inverting [WayBack] TInvokableClassRegistry.RegisterInterface.
This is the class helper I wrote:
type
TInvokableClassRegistryHelper = class helper for TInvokableClassRegistry
public
function GetInterfaceNamespace(Info: PTypeInfo): string;
end;
function TInvokableClassRegistryHelper.GetInterfaceNamespace(Info: PTypeInfo): string;
var
InfoGuid: TGUID;
begin
// call like `Result := InvRegistry.GetInterfaceNamespace(TypeInfo(MySoapInterfaceType));`
InfoGuid := GetTypeData(Info)^.Guid; // uses TypInfo; see https://stackoverflow.com/questions/8439246/is-it-possible-to-get-the-value-of-a-guid-on-an-interface-using-rtti
Result := GetNamespaceByGUID(InfoGuid);
end;
It would have been a lot easier if TInvokableClassRegistry.GetIntfIndex has been public, because then [WayBack]TInvokableClassRegistry.GetRegInterfaceEntry could have been used.

Though the field-types mentioned in the problem and solution are equal (so either is wrong), the solution in [WayBack] I have a little problem with FireDAC and the TStringField and TWideStringField design time generation… – Juan C. Cilleruelo – Google+ pointed out by Jeff Weir is interesting: FireDAC supports conditionals that depend on the DBMS back-end, so you can differentiate between them.
The feature is called Conditional Substitution and has been present ever since AnyDAC (which got bought by Embarcadero, transformed into FireDAC, then after Idera bought Embarcadero, the main developer got pink-slipped).
The AnyDAC documentation is in the wayback machine, though you have to disable the onload event in order to read it.
The [Archive.is] XE5: Preprocessing Command Text (FireDAC) – RAD Studio documentation is not much different from the current state [Archive.is].
More background reading is at [WayBack] www.freepascal.org/~michael/articles/anydac2/anydac2.pdf and Cary Jensen covered it in his 2017 course on FireDAC of which you can see the free ToC.
Example from that thread:
SELECT ART.CD_ITEM ,
ART.CD_FAMILY ,
ART.CD_CATALOGUE ,
CAT.DS_CATALOGUE ,
FAM.DS_FAMILY ,
{IF MSSQL}
CASE WHEN EXISTS(SELECT 1 FROM CONFIGURATIONS COM WHERE COM.CD_PARENT = ART.CD_ITEM)
THEN CAST('Y' AS NVARCHAR)
ELSE CAST('N' AS NVARCHAR)
END HAS_CONFIGURATION ,
{fi}
{IF FIREBIRD}
CASE WHEN EXISTS(SELECT 1 FROM CONFIGURATIONS COM WHERE COM.CD_PARENT = ART.CD_ITEM)
THEN 'Y'
ELSE 'N'
END HAS_CONFIGURATION ,
{fi}
ART.DS_ITEM ,
ART.CD_TAX ,
TAX.DS_TAX ,
TAX.PRC_TAX ,
...
Given the problem statement, the casts likely should have been VARCHAR instead of NVARCHAR, but the construct can be very powerful.

Idea for FOSS projects. Register your project/product name as a trademark and only use it for official, stable releases. Have a different name for your not-(yet)-stable Code.
Put trademark agreements in place. Everyone who uses your trademarked name for services based on your code has to pay. Everybody using the non-stable code is free to do so, but cannot use your trademarked name.
With lots of interesting comments:

A while ago, I had an error like this when debugging plugins:
Project bds.exe raised exception class EOSError with message ‘System Error. Code: 183.
Cannot create a file when that file already exists’.
It got was raised when [WayBack] GetLastError returned ERROR_ALREADY_EXIST which according to [WayBack] System Error Codes (0-499) (Windows) has this description:
ERROR_ALREADY_EXISTS
- 183 (0xB7)
- Cannot create a file when that file already exists.
The last line is the same description that [WayBack] FormatMessage returns. And it put me on the wrong foot as it wasn’t a file, but a mutex that was created: indeed [WayBack] CreateMutex documents it:
If the mutex is a named mutex and the object existed before this function call, the return value is a handle to the existing object, GetLastError returns ERROR_ALREADY_EXISTS, bInitialOwner is ignored, and the calling thread is not granted ownership. However, if the caller has limited access rights, the function will fail with ERROR_ACCESS_DENIED and the caller should use the OpenMutex function.
In the mean time, the plugin doesn’t raise that as an exception any more.
