Encoding for server side sorting and virtual list view

["John Liang" <John.Liang@openwave.com>]

HI there,

For RFC2891(server side sorting) and the draft of Virutal
List View, Do both client requests of these two controls 
require DER encoding(Distinguished Encoding Rules)? 
Is a BER encoded request also acceptable at this case?

If only DER is allowed, then for SortKeyList in Server Side
Sorting, the tag of "orderingRule [0] MatchingRuleId OPTIONAL"
should be 0x80 or 0xA0?

Same question for VirtualListViewRequest, the tag of 
 CHOICE {
	byoffset [0] SEQUENCE {
	  offset       INTEGER (0 .. maxInt)
	  contentCount INTEGER (0 .. maxInt)
should be 0x80 or 0xA0?

The Netscape Java API uses 0x80 for Server Side Sorting 
and 0xA0 for Virtual List View? Any reson for the difference?

Thanks,
