Thanks Sandy...I appreciate the response.  I hadn't read over the  
full doc yet and had missed the defaultAttribute.  So with  
defaultAttribute, it looks like I can just define an attribute group  
that includes <anyAttribute> and all is well.

In some ways, it might have made sense if <anyAttribute> was allowed  
in <openContent> so that <openContent> could control all open content  
(elements and attributes) while defaultAttribute was only for  
specific attribute groups (even if they include <anyAttribute>), but  
in the end as long as XML Schema 1.1 is providing open content for  
both elements and attributes then I'm happy :-)

Thanks again,
Rod

Rob,

Search for "defaultAttributes". :-)

It's a valid question whether <openContent> and "defaultAttributes"  
should be combined, but the capability is there.

We went further than just allowing default <anyAttribute>, because  
there are cases where people need to allow specific attributes  
everywhere (e.g. xml: ones).

Thanks,

Question on <openContent> and <anyAttribute>









Hello,

The addition of the <openContent> element in XSDL 1.1 is wonderful
and will greatly simplify extending XML Schemas.

However, I was wondering why the <openContent> element doesn't allow
for <anyAttribute> to be specified as well as <any> so that XML
Schemas can be easily extended with new attributes just at they can
now be easily extended with new elements?  It is certainly much more
common for new elements to be added, so I'm definitely thankful to
have <openContent> available at all, but I'm just curious why
<anyAttribute> support wasn't included as well.

Thanks and best regards,
Rod Hughes
