[Simple-support] Attribute field for "default" field

[A K <ak....@gm...>]

Hi,

I have the below declaration for the attrubute.
*

<xs:attribute type="xs:int" use="optional" default="50000"name="tagname1"/>
<xs:attribute type="xs:int" use="optional" default="1" name="tagname2"/>*
*xs:attribute type="xs:boolean" use="optional" default="true"name="tagname3"
*


The way we provide annotations is as below:

 @Attribute(required=false)
 private *Integer tagname1*;
 @Attribute(required=false)
 private *Integer tagname2*;
 @Attribute(required=false)
private Boolean *tagname3*;


Does *default="50000" has any significance? is there any field in attribute
to provide "default" data, like we give "required=false" for "use=optional"?
