validation of SIA 2

[Pierre Le Sidaner]

Hi Mark

Thank you for you feed back
It don't seem so clear for me I try to take some time to look at it more 
carefully.
would it be relevant to discuss 10 mn during next interop in Apps or in 
Semantic to define what should be helpful to have in the VOtable Header 
to validate it
Some parser failed when VOTable are not valid and it a lot of time loose 
in developing applications, not all developers have your VO skill.

I'll come back with what I have understood at the end of the week or 
beginning of the next
Regards
Pierre
