[Vtd-xml-users] update-operation impact, if any?

[Sun, V. <vs...@am...>]

Wondering what is frequent update/insert impact for vtd-xml :

*=09
	Does XMLModifier directly manipulating the underlying byte[]?
How does it handle inserting new data fragment? create a new memory
block to combine both of them? or just track the new block with the
token? Is there a performance benchmark on update operation comparison
with the other implementation?
*=09
	How will these newly inserted fragments impact the overall
navigation performance?=20
*=09
	How does the update operation impact the existing bookmarks?=20
*=09
	Can we associate multiple VTDNav with the VTDGen? Regardless,
how will the update operation impact the existing VTDNav ? (the
currentIdnex for example)

Thanks.
