Re: new version of inventory catalog XML

Hi Tom,

There's some pretty good discussion of the attribute-vs-element issue at


In particular, I like the last paragraph of the "Sperberg-McQueen" comments
which suggests that it really doesn't matter all that much.

Basically, most seem to agree that it depends on how the designer plans to use
the XML. In the case of the inventory catalog XML, sub-elements were used to
hierarchically organize the datasets and attributes were used for just about
everything else (except for free text).
