Receive an object for locating the origin of SAX document events.
SAX parsers are strongly encouraged (though not absolutely
required) to supply a locator: if it does so, it must supply
the locator to the application by invoking this method before
invoking any of the other methods in the ContentHandler
interface.
The locator allows the application to determine the end
position of any document-related event, even if the parser is
not reporting an error. Typically, the application will
use this information for reporting its own errors (such as
character content that does not match an application's
business rules). The information returned by the locator
is probably not sufficient for use with a search engine.
Note that the locator will return correct information only
during the invocation of the events in this interface. The
application should not attempt to use it at any other time.
Params: - locator – An object that can return the location of
any SAX document event.

Begin the scope of a prefix-URI Namespace mapping.
The information from this event is not necessary for
normal Namespace processing: the SAX XML reader will
automatically replace prefixes for element and attribute
names when the http://xml.org/sax/features/namespaces
feature is true (the default).
There are cases, however, when applications need to
use prefixes in character data or in attribute values,
where they cannot safely be expanded automatically; the
start/endPrefixMapping event supplies the information
to the application to expand prefixes in those contexts
itself, if necessary.
Note that start/endPrefixMapping events are not
guaranteed to be properly nested relative to each-other:
all startPrefixMapping events will occur before the
corresponding startElement event, and all endPrefixMapping
events will occur after the corresponding endElement event,
but their order is not guaranteed.
Params: - prefix – The Namespace prefix being declared.
- uri – The Namespace URI the prefix is mapped to.

Receive notification of a skipped entity.
The Parser will invoke this method once for each entity
skipped. Non-validating processors may skip entities if they
have not seen the declarations (because, for example, the
entity was declared in an external DTD subset). All processors
may skip external entities, depending on the values of the
http://xml.org/sax/features/external-general-entities and the
http://xml.org/sax/features/external-parameter-entities
properties.
Params: - name – The name of the skipped entity. If it is a
parameter entity, the name will begin with '%'.
