6. How XML Makes it Work We Identify key features
Give each unique feature a unique XML tag
Link each tag to other info (lat/lon, images)
Identify references to outside data
Create XML tags for each type of outside ref.
Map tags to external sources (CFR’s, URL’s…)

For craft approaching Portsmouth,
the large hotel with a charted cupola
at the southwest end of New Castle Island
is prominent. Other landmarks are: the
stone building and
square tower of the former
naval prison and the water tank on
Seavey Island; Whaleback Light;
the weathered buildings with conspicuous
cupola of the abandoned Coast Guard station
on Wood Island;
and numerous standpipes, elevated tanks, church
