Thanks

Did some small tests. It might not work for all cases, but can be a start:

CdtDiff(cdt1, cdt2):
=with(
local!fieldNames: apply(xpathsnippet(_, "name(*)"), xpathsnippet(toxml(ri!cdt1), "/*/*")),
apply(rule!CdtDiffField(ri!cdt1, ri!cdt2, _), local!fieldNames)
)

CdtDiffField(cdt1, cdt2, fieldName):
=with(
local!fieldOneType: runtimetypeof(index(ri!cdt1, ri!fieldName, null)),
local!fieldTwoType: runtimetypeof(index(ri!cdt2, ri!fieldName, null)),
local!fieldOneExits: tostring(index(ri!cdt1, ri!fieldName, "x_#")) <> "x_#",
local!fieldTwoExits: tostring(index(ri!cdt2, ri!fieldName, "x_#")) <> "x_#",
if(and(local!fieldOneExits, local!fieldTwoExits, local!fieldOneType = local!fieldTwoType),
if(local!fieldOneType < 1000,
{field: ri!fieldname, same: ri!cdt1[ri!fieldName] = ri!cdt2[ri!fieldName]},
{field: ri!fieldname, children: apply(rule!CdtDiff(_,_), merge(ri!cdt1[ri!fieldName], ri!cdt2[ri!fieldName]))}
),
false
)
)
