Michael Glavassevich resolved XERCESJ-1090:
-------------------------------------------
Resolution: Fixed
Looking back through the CVS change logs (see v1.28 of XMLSchemaValidator) it
seems the WG once had a different interpretation of what the "empty" content
type means. In addition to rejecting comments, Xerces was also rejecting
processing instructions. Both of these bugs should be fixed now. Thanks.

> Key: XERCESJ-1090
> URL: http://issues.apache.org/jira/browse/XERCESJ-1090
> Project: Xerces2-J
> Type: Bug
> Components: XML Schema Structures
> Versions: 2.7.0
> Environment: win2k, jod 1.5.0_01-b08
> Reporter: Paul V. Biron
> Assignee: Michael Glavassevich
> Priority: Minor
>
> Section 3.1.4 of Structures says:
> [Definition:] ... the initial value of an element information item
> is the string composed
> of, in order, the [character code] of each character information
> item in the [children] of
> that element information item.
> The above definition means that comments and processing
> instructions, even in the
> midst of text, are ignored for all ·validation· purposes.
> However, xerces 2.7.0 complains about comments within elements with empty
> content models.
