[OT] Do you see a problem in this serialization format ?

[Basile B. via Digitalmars-d]

I had to make a custom format because

- XML is not readable (think by hand edition; setting file)
- JSON is not good to represent D data types (an object must be 
created for each data, currently i have a json writer I could 
post a sample if you don't get what i mean)

I will use it as for Object Pascal streaming, to store the 
properties of the visual objects. The serializer uses a custom 
RTTI system instead of traits code. A factory could be used to 
create sub objects.

============================= SAMPLE 
===============================

Object root = "TextEn"
{
        Alignment alignment = "none"
        float width = "200"
        float height = "75"
        float left = "10"
        float top = "180"
        bool visible = "true"
        bool focusable = "true"
        bool wantMouse = "true"
        string caption = "Lorem ipsum"
        Brush fill = "Brush"
        {
                FillKind fillKind = "uniform"
                uint color = "4294965965"
                GradientKind gradientKind = "horizontal"
                FillAdjustment fillAdjustment = "none"
                Gradient gradient = "Gradient"
                Bitmap bitmap = "Bitmap"
                {
                        Stream data = "[]"
                }
        }
        Brush stroke = "Brush"
        {
                FillKind fillKind = "uniform"
                uint color = "4287245282"
                GradientKind gradientKind = "horizontal"
                FillAdjustment fillAdjustment = "none"
                Gradient gradient = "Gradient"
                Bitmap bitmap = "Bitmap"
                {
                        Stream data = "[]"
                }
        }
        Pen pen = "Pen"
        {
                float width = "1"
                Dash dash = "none"
                Join join = "miter"
                LineCap cap = "butt"
        }
        Font font = "Font"
        {
                float size = "32"
                string name = "/usr/share/fonts/truetype/FreeMono.ttf"
        }
        Justify justify = "left"
}

====================================================================

The structure is simple, I'm not a language technician but the 
grammar would be:
({ } = " are unamed literals)

escapes
  \" \n
Type
   [\S]+
name
   [\S]+
value
   "[escapes ^"]+" opt ObjectEntry

Entry
    Type name = value

Entries
    Entry0
    Entry1
    ....
    EntryN

ObjectEntry
   { Entries }

sub Object declarations may look strange, eg

    Stuff stuff = "Stuff" {}

instead of

    Stuff stuff = {}

but actually it was easier to parse whithout special case. For 
example once I reach the terminal double quote I just have to 
read while white and to check the character. If it's an opened 
brace I know that I'll have to read a ObjectEntry, otherwise it's 
Entry.

So, what do you think, is there any design flaw ?
