Description C. M. Sperberg-McQueen 2006-01-20 03:48:19 UTC 
A Note in Structures section 2.2.3.2 says:

  Note: XML Schema: Structures ·content models· are similar to but 
  more expressive than [XML] content models; unlike [XML], XML 
  Schema: Structures applies ·content models· to the ·validation· 
  of both mixed and element-only content.

This is incorrect as it stands:  the use of content models to validate
both mixed and element content is common to XML DTDs and XML Schema.
What is different is that XML Schema does not restrict the form of
content models for mixed content in the same way as XML DTDs.

I think the statement should be corrected (although I do not now
propose specific alternative wording).
Comment 1 C. M. Sperberg-McQueen 2006-10-23 13:18:51 UTC 
A possible wording to correct the inaccuracy in the existing
Note:

  Note: XML Schema: Structures content models are similar to but
  more expressive than [XML] content models; unlike [XML], XML
  Schema: Structures does not restrict the form of content models
  describing mixed content.
Comment 2 C. M. Sperberg-McQueen 2006-10-27 21:13:47 UTC 
On its telcon today, the WG agreed to the wording proposal in
comment #1.
