While working on my Delphi: First try on an XSD for .groupproj files, I bumped into an error `Namespace ” is not available to be referenced in this schema`.
I added a targetNamespace attribute to the GroupProj.xsd so the .grouproj files would use the right namespace.
That resulted into two funny errors:
- Namespace ” is not available to be referenced in this schema.
Visual Studio (which I normally use for editing XSD) would only throw this error on these elements:
<xsd:element ...>
So it would not throw them on nodes using the empty namespace.
That was really confusing! - When validating .grouproj files using this GroupProj.xsd, I would get this error for all .groupproj files:
System.Xml.Schema.XmlSchemaValidationException: Type ‘<type>’ is not declared. (in this case for ‘<type>’ ‘ProjectType’).
That was odd too: the ‘ProjectType’ was indeed declared, and should be valid.
I could hardly find any information about the latter error, but the former gave a few useful hits.
Thanks User weston – Stack Overflow. for answering this: it made me smack to my head (like usual, a case of EBCAK). Read the rest of this entry »
