package com.sun.org.apache.xerces.internal.xs;
This interface provides access to the post schema validation infoset for an
API that provides a streaming document infoset, such as SAX, XNI, and
others.
For implementations that would like to provide access to the PSVI in a
streaming model, a parser object should also implement the
PSVIProvider interface. Within the scope of the methods
handling the start and end of an element, applications may use the
PSVIProvider to retrieve the PSVI related to the element and
its attributes.

public interface PSVIProvider {
Provides the post schema validation item for the current element
information item. The method must be called by an application while
in the scope of the methods which report the start and end of an
element. For example, for SAX the method must be called within the
scope of the document handler's startElement or
endElement call. If the method is called outside of the
specified scope, the return value is undefined.
Returns: The post schema validation infoset for the current element. If
an element information item is valid, then in the
post-schema-validation infoset the following properties must be
available for the element information item: The following
properties are available in the scope of the method that reports
the start of an element: {element declaration}, {validation
context}, {notation}. The {schema information} property is
available for the validation root. The {error codes} property is
available if any errors occured during validation. The following
properties are available in the scope of the method that reports
the end of an element: {nil}, {schema specified}, {normalized
value},{ member type definition}, {validity}, {validation attempted}
. If the declaration has a value constraint, the property {schema
default} is available. The {error codes} property is available if
any errors occured during validation. Note: some processors may
choose to provide all the PSVI properties in the scope of the
method that reports the end of an element.

public ElementPSVI getElementPSVI();
Provides AttributePSVI given the index of an attribute
information item in the current element's attribute list. The method
must be called by an application while in the scope of the methods
which report the start and end of an element at a point where the
attribute list is available. For example, for SAX the method must be
called while in the scope of the document handler's
startElement call. If the method is called outside of
the specified scope, the return value is undefined.
Params: - index – The attribute index.
Returns: The post schema validation properties of the attribute.

Provides AttributePSVI given the namespace name and the
local name of an attribute information item in the current element's
attribute list. The method must be called by an application while in
the scope of the methods which report the start and end of an element
at a point where the attribute list is available. For example, for

handler's startElement call. If the method is called

Params: - uri – The namespace name of an attribute.
- localname – The local name of an attribute.
Returns: The post schema validation properties of the attribute.
