there is the same semantic that you would have in a relational database
: if you would have a table named "Person" that contains 2 fields,
"Name" and "Age", what would be the semantic ?
if you agree that it must be understandable as a name and an age of a
person, this could be the same in the XML structure than in your RDBMS
but it's only convention, XML doesn't carry semantics itself
IMHO, i think that when a convention has been made on the meaning of
elements and attributes, people that have the knowledge of the
convention consider that the structure has semantics ; they can now
build applications with these considerations
just like with RDBMS
