Steve Lawrence updated DAFFODIL-2033:
-------------------------------------
Description:
The defaultValue attribute in the dfdl:defineVariable element is allowed to
contain either a DFDL expression or a logical value, for example, the following
are equivalent
{code:xml}
<dfdl:defineVariable name="foo" type="xs:boolean" defaultValue="false" />
<dfdl:defineVariable name="foo" type="xs:boolean" defaultValue="{ fn:false() }"
/>{code}
However, Daffodil always treats the defaultValue as an expression, assuming
curly braces if they are missing. So in the case ofthe logical value, Daffodil
tries to set the default value to
{code:xml}
{ false }{code}
Which isn't valid and result in an error. Instead, we should only treat the
defaultValue as an expression if curly braces exist. Otherwise, we should
convert the logical value to the the type using standard string-to-type XML
conversion methods.
