RPGle - i wish i could do some 'Reflection'

Hello everyone,

I wish i could do some reflection using RPGLe.
By reflection, I mean :
'The process or mechanism of determining the capabilities of an object at run-time.'

Imagine you have this datastructure :

D DS_Format DS Qualified Based(pDS_Format)
D Type 20I 0 Inz(1)
D Label 50A Inz('myLabel')
D Description 5000A Inz('myDescription')

With a reflection api, I could do this :
Reflection_ListSubfields(DS_Format);
=> return this array : { 'Type', 'Label', 'Description' }
And then, I could do :
Reflection_GetSubfield(DS_Format : 'Label');
=> return 'myLabel'

I wish i could do this too :
Reflection_GetSubfieldType(DS_Format : 'Label');
=> return 'A'
Reflection_GetSubfieldLength(DS_Format : 'Label');
=> return 50
Reflection_GetSubfieldPrecision(DS_Format : 'Type');
=> return 0


With this, I expect I could do something like this (with some little work) :
SerializeXml(DS_Format); //I build xml with one line of code !
And get :
<DS_Format>
<Type>1</Type>
<Label>myLabel</Label>
<Description>myDescription</Description>
</DS_Format>
And conversely with DeserializeXml(myXml);

Reflection would help me to build really cool apis.
Is there any way ?
