Q: You said that & is special and I
need to use the entity & in its place,
but to type in any entity I have to use a &.

entity has a number too. What do I use

entities have names, so in those cases your
only choice is to use the number.
Just remember to use & anytime you type in
an entity, and if you really need an & in your
content, use & instead.
