[DDI-SRG] Namespaces and standard prefixes

[Wendy Thomas]

Pascal,

The practice up to this point has been single letters r: l: s: etc. as 
used in the samples and import stateements to date. The use of a letter 
number combination for the BaseRecordLayout substitution groups seems to 
be the most logical in that this is an area where we would expect future 
growth. Trying to provide them all with unique prefixes that relate to 
their names is really not practical. It looks like the other major change 
was to use dc for dublincore (which is their standard prefix).
