May be my English is not so good, sorry :P I meant, standard serializati=
on  =

for structured data, structured as a tree, and potentially as a graph, v=
ia  =

IDs and IDREFs.

That's the role of document type definitions, which can be either DTD (t=
he  =

legacy and most widely used solution, which is inherited from the SGML  =

era), or XSD (the most standard one along with DTD) or RNG and Schematro=
n.

No? You don't need tool to check Ada source legality?
