Hi,
during installation of the eclipse subversion plugin, I 'inherited' the
XSD plugin too. Now my eclipse 'problems' list is showing errors in
schemas in my project.
I have googled and searched this mailing list without finding a
solution. Perhaps someone can recognise what basic mistake I'm making -
and I'm sure it must be basic :(
XSD: Attribute reference 'http://www.w3.org/XML/1998/namespace#lang' is
unresolved
comes from this line of schema:
<xs:attribute ref="xml:lang" default="en"/>
which imports the schema mentioned in the error msg like so:
<xs:import namespace="http://www.w3.org/XML/1998/namespace"
schemaLocation="http://www.w3.org/2001/xml.xsd"/>
I have actually downloaded the xml.xsd schema and placed it in the same
directory, and I have this directory loaded as a class folder resource
in the .classpath for my project like so:
<classpathentry kind="lib" path="docs/Design/schemas"/>
Thanks
Adam

I tried this in a sample and it loaded fine. It sure looks correct.
Maybe the problem is that your application doesn't have access to the
web in order to load the schema...

I'm definitely online all the time - but I do have a firewall - what

know I have problems with stuff like instant messenger.
How can I force a try in Eclipse? Will a refresh do it?

I'm really not sure what's doing causing your schema to be validated

try again. Certainly changing the time stamp of the file and refreshing
should do the trick...

example with the Sample editor provided by XSD?

There are warnings too:
XSD: The location 'http://www.w3.org/2001/xml.xsd' has not been resolved
I can't see from looking in the help why XSD is outputting any errors or
warnings at all or what exactly Eclipse is doing when it finds .xsd
files while building the project.
Eclipse has associated .xsd file with the Sample XSD Editor and looking
at the schema, Ecilpse shows the warnings and errors at the appropriate
lines.
This seems to contradict your statement about XSD providing no autmoated
validator, surely?

Unfortunately I am completely in the dark about the way that Eclipse is
behaving and I'm hoping to get the info from you or someone here! Do you
think I would have more success on the eclipse user list?
Id gladly send you the complete schema set just to test it quickly but I

little about the way other plugins use XSD, so your question should
really be directed to the folks who implemented this automatic

is invalid but when included in some context becomes valid, or vice
versa, so simply validating schemas by scanning for them and validating
each separately is a design with some issues... Your problem really
sounds like an inability to fetch the schema from the http location...

Does this tell you anything?

I got rid of XMLSpy on the basis that it was a memory hog and not open
source, and then I discovered that the xsd plugin had the editor. Did
those schemas arrive again properly?

Your schema location was http.
I'm really not sure what's doing causing your schema to be validated
automatically (XSD doesn't provide such support) nor what would make it
try again. Certainly changing the time stamp of the file and refreshing
should do the trick...
