----------------------------------------

             Summary: Incorrect prefix suggested for bad steps in DPath paths
                 Key: DAFFODIL-2115
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2115
             Project: Daffodil
          Issue Type: Bug
          Components: Diagnostics
            Reporter: Brandon Sloane
         Attachments: a.dfdl.xsd, b.dfdl.xsd

Consider the following (incorrect) DFDL snippet:

 
{quote}<xs:element name="root" dfdl:lengthKind="implicit">
 <xs:complexType>
 <xs:sequence>
 <xs:element ref="a:a_element" />
 <xs:element name="b" type="tns:b_type" dfdl:inputValueCalc="\{ ../a_element }" />
 </xs:sequence>
 </xs:complexType>
 </xs:element>
{quote}
Note that the dfdl:inputValueCalc should specify the namespace of the element it is referring to "a:a_element".

In attempting to compile the above, Daffodil reports the error as:
{quote}[error] Schema Definition Error: No element corresponding to step {}a_element found. Possibilities for this step include: tns:a_element, {}b.
{quote}
Following Daffodils advice, results in a more reasonable suggestion:

 
{quote}
[error] Schema Definition Error: No element corresponding to step tns:a_element found,but elements with the same local name were found (a:a_element).Perhaps a prefix is incorrect or missing on the step name?
{quote}
 

Schema needed to reproduce is attached. Reproduce with:
{quote}daffodil save-parser -s b.dfdl.xsd parser.bin
{quote}
