the <span class="RktVar">table</span> association list. Each entry in <span class="RktVar">table</span>
should be a list whose first element is a keyword and whose subsequent
elements are procedures for checking the arguments following the
keyword. The keyword’s arity (number of arguments) is determined by
the number of procedures in the entry. Only fixed-arity keywords are
supported.</div></p><p>Parsing stops normally when the syntax list does not have a keyword at
its head (it may be empty, start with a non-keyword term, or it may be
a non-list syntax object). Two values are returned: the parsed
<a href="#%28tech._option%29" data-pltdoc="x">options</a> and the rest of the syntax (generally either a
syntax object or a list of syntax objects).</p><p>A variety of errors and exceptional conditions can occur during the
parsing process. The following keyword arguments determine the
behavior in those situations.</p><p>The <span class="RktPn">#:context</span><span class="stt"> </span><span class="RktVar">ctx</span> argument is used to report all errors in

keyword options are not allowed. If a duplicate is seen, the keyword’s
associated check procedures are not called and an <a href="#%28tech._incompatibility%29" class="techoutside" data-pltdoc="x"><span class="techinside">incompatibility</span></a> is
reported.</p><p>The <span class="RktVar">incompatible</span> argument is a list of incompatibility

in the entry, an <a href="#%28tech._incompatibility%29" class="techoutside" data-pltdoc="x"><span class="techinside">incompatibility</span></a> is reported.</p><p>Note that including a keyword in an incompatibility entry does not
prevent it from occurring multiple times. To disallow duplicates of
some keywords (as opposed to all keywords), include those keywords in
the <span class="RktVar">incompatible</span> list as being incompatible with
themselves.
