Tags vs PCDATA

[Frank Boumphrey]

Hi,
a full review of this question can be found at

It appears that there is no correct answer, except if you use an attribute,
then the data will not be visible to the reader when the tags are stripped
off.

>As I see it, the tag type has the advantage that it is the same tag
>(eg. <Name>) in the query as in the answer. You can limit the queries to
