[Exist-open] validation report: error coordinates

[Ron V. d. B. <ron...@ka...>]

Hi,

In general, the validation:validate-report() function is working great, 
but I'm confused about the coordinates (line and column numbers) of the 
errors reported.

Given a document

<TEI xmlns="http://www.tei-c.org/ns/1.0">
<p>this is a paragraph with <div>a <choice>div</choice></div></p>
</TEI>

stored at '/db/test/test.xml' and a teilite.xsd schema stored at 
'/db/test/teixlite.xsd'.

I get different results when issuing following commands in the Java 
client (latest SVN trunk):

* XQuery 1:
let $query := document('/db/TBE/test.xml')
return validation:validate-report($query, 
xs:anyURI('/db/TBE/schema/teilite.xsd'))

RESULT 1:
<report>
    <status>invalid</status>
    <namespace>http://www.tei-c.org/ns/1.0</namespace>
    <time>15</time>
    <message level="Error" line="1" column="45">cvc-complex-type.2.4.a:

'{teiHeader}' is expected.</message>

* XQuery 2:
validation:validate-report(xs:anyURI('/db/TBE/test.xml'), 
xs:anyURI('/db/TBE/schema/teilite.xsd'))

</report>

Notice the difference in line and column numbering. The error 
coordinates for the first XQuery are consistent, but particularly for 
the second XQuery there seems to be no logic in the imprecision. Any 
clarifications / suggestions?

I know the lexical form of an XML document is trivial, but in this case 
it seems to matter, for I'm trying to build a validation service that 
renders a visual representation of the validation results.

Thanks for any help or insight,

Ron
