- Edit core/tests/AH.dfdl.xsd in eclipse. Notice that it uses xmlns="http://www.w3.org/2001/XMLSchema", which is the usual name space for XML Schema.
- Note that the file extension ".dfdl.xsd" is the standard way to identify a DFDL schema file.
- Change one of the dfdl:inputValueCalc properties and misspell the property name. Save the file and you will NOT see any validation error.
- Change one of the attributes of the dfdl:defineVariable element, such as remove the name attribute and put in a ref="foo" attribute. Save, and you should see a validation error.
- Validation using the standard XML Schema URL will NOT validate short form DFDL annotations, nor will it care if you put a long form annotation element named dfdl:foobar. But if you do get the name of a DFDL annotation element correct, then it will validate the properties on that annotation element.
Eclipse Unicode Setup
On Linux, UTF-8 and good unicode fonts are the default.
On Windows, a US install normally doesn't default to a Unicode friendly environment. One of the features of the Scala programming language is that it is completely unicode aware.
But, to make a USA windows default install of Windows itself, and Eclipse unicode friendly, you have to take a few steps.
These are described in the solution to this issue: https://opensource.ncsa.illinois.edu/jira/browse/DFDL-81. See the comments at the bottom for the settings.
