Agree. This would be useful in many cases.

This is difficult to do in the actual AST building, but very easy to do in the generation of the output XML:
procedure NodeToXMLInternal(const Node: TSyntaxNode; const Indent: string);
var
HasChildren: Boolean;
NewIndent: string;
Attr: TPair<TAttributeType, string>;
ChildNode: TSyntaxNode;
NodeOK: boolean;
begin
NodeOK:= not(Node.Typ in Exclude) and (Node.Typ in InternalInclude);
HasChildren := Node.HasChildren;
if NodeOK then begin
if Formatted then begin
NewIndent:= Indent + ' ';
Builder.Append(Indent);
end;
Builder.Append('<' + UpperCase(SyntaxNodeNames[Node.Typ]));
if (Node is TCompoundSyntaxNode) then begin
Builder.Append(' begin_line="' + IntToStr(TCompoundSyntaxNode(Node).Line) + '"');
Builder.Append(' begin_col="' + IntToStr(TCompoundSyntaxNode(Node).Col) + '"');
Builder.Append(' end_line="' + IntToStr(TCompoundSyntaxNode(Node).EndLine) + '"');
Builder.Append(' end_col="' + IntToStr(TCompoundSyntaxNode(Node).EndCol) + '"');
end else begin
Builder.Append(' line="' + IntToStr(Node.Line) + '"');
Builder.Append(' col="' + IntToStr(Node.Col) + '"');
end;
for Attr in Node.Attributes do Builder.Append(' ' + AttributeName[Attr.Key] + '="' + XMLEncode(Attr.Value) + '"');
if HasChildren then Builder.Append('>')
else Builder.Append('/>');
if Formatted then Builder.AppendLine;
end;
for ChildNode in Node.ChildNodes do NodeToXMLInternal(ChildNode, NewIndent);
if NodeOK then begin
if HasChildren then begin
if Formatted then Builder.Append(Indent);
Builder.Append('</' + UpperCase(SyntaxNodeNames[Node.Typ]) + '>');
if Formatted then Builder.AppendLine;
end;
end;
end;
begin
if Include = [] then InternalInclude:= [ntUnknown..ntWrite]
else InternalInclude:= Include;
NodeToXMLInternal(Node, '');
end;
