2006-02-18T04:04:04ZA binding is given eg in a proof or query result
The step of taking one statement out of a formula.
The step is identified by the :gives formula (the statement)
and the :because step's :gives formula (the formula extracted
from).
The formula given was derived from parsing a
resource.A Proof step is the last step in the proof,
a step which :gives that which was to be proved.
Typically a document will assert just one :Proof,
which a checker can then check and turn into
the Formula proved - Q.E.D. .
A step in a proof.
See :gives for the arc to the formula proved at this step.
gives the step whose data was input to this step.
This binding binds its variable to this term.
A step whose data was used in building this conjunctionThe source document which was parsed.
The given string is that used as the identifier of the variable
which is bound by this binding. The variable name has to be given as
a string, rather than the variable being put here, or the variable
would be treated as a variable.
