Persistent Schema Conversion

Question

I am trying to increase the version number of the persistent data from 1.0 to 2.0 using a null conversion as described in the documentation. My problem is that when opening a document with the old version it it marked as converted and when saving it comes and asks for file to save as (as a save as). Is it not possible to do schema conversions without forcing the user to overwrite documents manually?
Changes done to the .fr file:
resource PluginVersion (kSDKDefPluginVersionResourceID)
kTargetVersion,
kKBWFPluginID,
kKBWFMajorVersion, kKBWFMinorVersion,
kSDKDefHostMajorVersionNumber, kSDKDefHostMinorVersionNumber,
2, 0,
{ kInDesignProduct, kInCopyProduct },
{ kWildFS },
SDK_DEF_MAKE_VERSIONSTRING(kKBWFMajorVersion, kKBWFMinorVersion, kKBWFBugfixVersion, kKBWFBuildNumber)
resource ClassDescriptionTable(kSDKDefClassDescriptionTableResourceID)
Class
kKBWFConversionProviderBoss,
kInvalidClass,
IID_ICONVERSIONPROVIDER,kSchemaBasedConversionImpl,
IID_IK2SERVICEPROVIDER, kConversionServiceImpl,
resource SchemaList(kSDKDefSchemaListResourceID)
// <none>
resource SchemaFormatNumber(kSDKDefSchemaFormatNumberResourceID)
{1, 0},
{2, 0},

Why did you add the SchemaList ?
The ww-data-conversion.pdf page 9 (Null Conversions) is only specific that there must not be any DirectiveList.
I do not see SchemaList mentioned there as either good or bad, IMO an omission.
No idea whether that solves your Save-As problem, as I'm currently working on application prefs.
