[oXygen-user] Validating XML instance with a Schema which imports another Schema

[Sorin Ristache]

Hello,

The error is in the schema HUD_HMIS_2_8.xsd located at

http://www.hmis.info/schema/2_8/HUD_HMIS_2_8.xsd

This schema references the type airs:tSiteService, that is 
the type tSiteService from the namespace 
"http://www.hmis.info/schema/2_8/AIRS_3_0_draft5_mod.xsd". 
The error is that the target namespace of the imported schema

http://www.hmis.info/schema/2_8/AIRS_3_0_draft5_mod.xsd

is "http://cse.unl.edu/~bkutsch/3_0_draft_d5.xsd" which does 
not match the namespace used in the import element in 
HUD_HMIS_2_8.xsd (line 10). That means the type tSiteService 
defined in AIRS_3_0_draft5_mod.xsd in the namespace 
"http://cse.unl.edu/~bkutsch/3_0_draft_d5.xsd" cannot be 
matched with the type reference used on line 828 of 
HUD_HMIS_2_8.xsd which needs a type tSiteService from the 
namespace 
"http://www.hmis.info/schema/2_8/AIRS_3_0_draft5_mod.xsd".

You do not need a validation scenario for a simple 
validation of an XML document against an XML Schema. It does 
not matter if the schema is local or remote. Oxygen will 
load it from the specified location. You should use a 
validation scenario in one of the two situations in which 
the User Manual recommends it but you are not in these 
situations:
