XLIFF validation on invalid XML character using <cp>

["Yoshito Umaoka" <yoshito_umaoka@us.ibm.com>]

Hi Rodolfo,

I was playing
with XLIFF validation service today - https://dev.maxprograms.com/Validation/

---
<xliffxmlns="urn:oasis:names:tc:xliff:document:2.0"version="2.0"srcLang="en"trgLang="fr">
<fileid="f1">
 
<unit id="u1">
 
  <segmentid="s1">
 
    <source>Test
<cphex="D800"/></source>
 
  </segment>
 
</unit>
</file>
</xliff>
---

The validation
service returns

---
File "test-cp.xliff"
is not valid XLIFF.

Reason: Valid XML character represented as <cp>
---

However, this
content should be valid. Unicode code point U+D800 (to U+DB7F) is reserved
as High Surrogates. The code point does not represent a valid XML character,
so <cp hex="D800"/> should be valid. (Of course, <cp
hex="D7FF"/> is invalid). I guess the validation service does
not check the range properly.

Thanks,
Yoshito
