NAME

       XML::Doctype::AttDef - A class representing a definition in an <!ATTLIST> tag

SYNOPSIS

	  $attr = $elt->attribute( $name ) ;
	  $attr->name ;

DESCRIPTION

       This module is used to represent <!ELEMENT> tags in an XML::Doctype object.  It contains <!ATTLIST> tags as well.

STATUS

       This module is alpha code.  It's developed enough to support XML::ValidWriter, but need a lot of work.  Some big things that are lacking
       are:

METHODS

       new
	      $dtd = XML::Doctype::AttDef->new( $name, $type, $default ) ;

       default
	      ( $spec, $value ) = $attr->default ;
	      $attr->default( '#REQUIRED' ) ;
	      $attr->default( '#IMPLIED' ) ;
	      $attr->default( '', 'foo' ) ;
	      $attr->default( '#FIXED', 'foo' ) ;

	   Sets/gets the default value.  This is a

       quant
	      $attdef->quant( $q ) ;
	      $q = $attdef->quant ;

	   Sets/gets the attribute quantifier: '#REQUIRED', '#FIXED', '#IMPLIED', or ''.

       name
	      $attdef->name( $name ) ;
	      $name = $attdef->name ;

	   Sets/gets this attribute name.  Don't change the name while an attribute is in an element's attlist, since it will then be filed under
	   the wrong name.

       default_on_write
	      $attdef->default_on_write( $value ) ;
	      $value = $attdef->default_on_write ;

	      $attdef->default_on_write( $attdef->default ) ;

	   Sets/gets the value which is automatically output for this attribute if none is supplied to $writer->startTag.  This is typically used
	   to set a document-wide default for #REQUIRED attributes (and perhaps plain attributes) so that the attribute is treated like a #FIXED
	   tag and emitted with a fixed value.

	   The default_on_write does not need to be the same as the default unless the quantifier is #FIXED.

SUBCLASSING

       This object uses the fields pragma, so you should use base and fields for any subclasses.
