Subject: [URN] about reserved character slash('/')

I'm a student interested in URN.

In RFC2141(URN Syntax), the character slash('/') is a reserved
character, so it cannot be used in URN syntax.

But in DOI(Digital Object Identifier) or Handle System, the character
slash is used.

I think the character slash is useful in distinguishing something from
others, or  expressing hierarchical relation. For example,
<urn:USA:university/UCLA/1999-1>
So I think the character slash is to be freed from reserved character.

How about your opinion?
