    schema: do not require name for certain pool types
    
    Pool types that have the VIR_STORAGE_POOL_SOURCE_NAME flag set
    allow omitting the <name> element and instead fill out the pool name
    from the <source><name> element.
    
    Relax the schema to make <name> optional for these pools.
    Expressing that at least one of these is required is out of scope
    of the schema.
