+Summary: Assorted System.Xml.XmlSchema fixes
+
+Attached are a couple of patches to the Mono System.Xml.XmlSchema
+implementation, which somewhat improve its operation.
+
+xmlschema-enumerator.patch:
+- XmlSchemaObjectEnumerator.cs: change an XmlSchema cast to XmlSchemaObject
+  to avoid an InvalidCastException every time the XmlSchema.Items property
+  is traversed.
+
+xmlschema-iscompiled.patch:
+- add actual handling of the XmlSchema.isCompiled member variable: reset it
+  in all routines that change the schema's textual description and set it
+  to true upon a successful run of the XmlSchema.Compile() method.
+- check for isCompiled at the start of the Compile() method; do not attempt
+  to compile the schema twice, adding the same objects to the Items hash.
+
+xmlschema-ann.patch
+- XmlSchemaAppInfo.cs: add the ability to read more than one XmlNode;
+- XmlSchemaAnnotation.cs: note that XmlSchemaAppInfo.Read() and
+  XmlSchemaDocumentation.Read() return with the reader positioned at
+  the respective element's end, *not* at the next element or at
+  the annotation end.  Thus, expect and swallow an EndElement for
+  'appinfo' or 'documentation', instead of choking while expecting
+  an EndElement for 'annotation'.
+
+xmldocument-skipread.patch
+- XmlDocument.ReadNode: check if the reader is already positioned at
+  an Element, and if so, do not do a Read() that will skip the start
+  tag of the element.  I am not completely sure that this will not
+  break anything, but it is needed for the appinfo implementation
+  if the latter should really support more than one XmlNode in an
+  <appinfo> element: in that case, we find that there is another node
+  only when the reader is positioned at its start, so when we call
+  XmlDocument.AppendChild(), we must not do another Read().
+
+The patches will be attached to this bug report as soon as it is filed;
+in the meantime, they are available at
