.SH DESCRIPTION
.IX Header "DESCRIPTION"
Filter copying the value of another field if the original value of this field
is empty.
.SH CAVEATS
.IX Header "CAVEATS"
If the original field contains an invalid value (a value that will be
constrained through a constraint) that invalid value will be copied to this
field (the field with the CopyValue filter).  So, the user has to change two
fields, or you can remove the invalid value in a custom constraint.
