            Bug ID: 25919
           Summary: unparsed-text-023 should not expect a static error
           Product: XPath / XQuery / XSLT
           Version: Recommendation
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XQuery 3 & XPath 3 Test Suite
          Assignee: oneil@saxonica.com
          Reporter: josh.spiegel@oracle.com
        QA Contact: public-qt-comments@w3.org

fn-unparsed-text-023 currently expects XPST0001 because $href is a relative URI
and the static base URI is undefined:

<test-case name="fn-unparsed-text-023" ...>
<description>Evaluates the "unparsed-text" function with the argument set as
follows: $href is a relative URI, static base URI undefined.</description>
<created by="Tim Mills" on="2011-11-28"/>
<environment>
   <static-base-uri uri="#UNDEFINED"/>
</environment>
<test><![CDATA[fn:unparsed-text("unparsed-text/text-plain-utf-8.txt")]]></test>
<result>
   <error code="XPST0001"/>
</result>
</test-case>

XPST0001 is a static error.  In general it is not possible to determine if the
value of $href is relative or not during static analysis so I don't think a
static error is appropriate. 

In this particular case it may be possible for an implementation to detect the
error during static analysis but this would still be a dynamic error that is
detected during static analysis (not a static error).  

Consequently, I also think that fn-unparsed-text-available-023 should return
false instead of expecting a static error:

<test-case name="fn-unparsed-text-available-023">
<description>Evaluates the "unparsed-text-available" function with the argument
set as follows: $href is a relative URI, static base URI
undefined.</description>
<created by="Tim Mills" on="2011-11-28"/>
<environment>
  <static-base-uri uri="#UNDEFINED" />
</environment>
<test>fn:unparsed-text-available("unparsed-text/text-plain-utf-8.txt")</test>
<result>
<error code="XPST0001"/>
</result>
</test-case>

http://www.w3.org/TR/2014/REC-xpath-functions-30-20140408/#func-unparsed-text-available

"... the function returns true if a call on fn:unparsed-text with the same
arguments would succeed, and false if a call on fn:unparsed-text with the same
arguments would fail with a non-recoverable dynamic error"

The following tests fall in this category:

  fn-unparsed-text-023 
  fn-unparsed-text-024
  fn-unparsed-text-lines-023 
  fn-unparsed-text-lines-024
  fn-unparsed-text-available-023 
  fn-unparsed-text-available-024

Thanks.
