abstract member IsSpecified : int -> bool

Parameters

The index of the attribute. The same index for the org.xml.sax.Attributes object passed to the startElement callback.

Attributes

Exceptions

If the index is invalid.

If this method is called from other IContentHandler methods.

Remarks

Returns false if the attribute was added by the validator.

This method provides information necessary for a javax.xml.parsers.DocumentBuilder to determine what the DOM tree should return from the org.w3c.dom.Attr#getSpecified() method.

The method may only be called by the startElement event of the org.xml.sax.ContentHandler that the application sets to the ValidatorHandler.

A general guideline for validators is to return true if the attribute was originally present in the pipeline, and false if it was added by the validator.
