# Updates

## Errata as of 2009-08-18

### U.1

#### Repeatable element ActionList types

The key constraint on ActionList added. An ActionList requires a unique value for a record key to function correctly. The key constraint is implemented in the XSD with xs:unique

#### SIF object primary key indicators

The primary key of a SIF object is identified in the XSD with xs:unique.

#### SIF_LogEntry/SIF_LogObjects/SIF_LogObject type change

The SIF_LogEntry/SIF_LogObjects/SIF_LogObject type changed to xs:any processContents="skip" minOccurs="0" maxOccurs="unbounded" to allow the SIF_LogEntry object report on invalid data objects and to allow SIF_Event change objects to be reported and validated against the Data Model XSD without errors when mandatory elements are not present.

# Known Issues

## Errata as of 2008-05-30

### E.1

#### Section 5.1.12 SIF_ExtendedQueryResults

The type of `SIF_ExtendedQueryResults/SIF_Rows/R/C` has been changed from `ExtendedContentType` to the new `SelectedContentType`. `SelectedContentType` is defined in similar fashion to `ExtendedContentType` but with `xs:any/@processContents` set to `skip` instead of `lax`. This type change prevents arbitrarily selected SIF elements from clashing with top-level common element definitions when differently defined elements share the same name.
