Re: [KEYPROV] XML to ASN.1 for attributes

["Tschofenig, Hannes (NSN - FI/Espoo)" <hannes.tschofenig at nsn.com>]

In XML it is more useful to have child elements rather than attributes.
The main reason is extensibility. When you want to define complex
structures then those cannot be added as attributes. 

I wonder whether a similar restriction replies to ASN.1
