[xml] Assorted regressions in libxml2 2.5.11

[Nicolai Langfeldt <janl linpro no>]

Hi,

With 2.5.11, running regression tests I run into some problems.


This first one fails on both Solaris 8/Sparc and Red Hat 7.3/Intel:

...
Testing length3_0_0
1c1
< compilation error

> compilation error: file ./test/schemas/length3_0.xsd line 5 element 
xs:element
 **** Not expected.  Unknown.
...
Testing po1_0_0

xsd:element
3a7
> compilation error: file ./test/schemas/po1_0.xsd line 51 element 
xsd:attribute
5d8
< Element purchaseOrder content check failed

This appears to be a lack in the tar ball:

Testing docbook_0
0a1,6
> ./test/relaxng/docbook_0.xml:16: warning: failed to load external 
entity "test/dtd/4.1.2/docbookx.dtd"
> ]>
>   ^
> ./test/relaxng/docbook_0.xml:1864: error: Entity 'copy' not defined
>              <sgmltag>&amp;copy;</sgmltag> &mdash; copyright sign 
(&copy;)
> 
    ^

This test passes on redhat 7.3, but it has docbookx.dtd installed 
otherwhere on the machine.  docbookx.dtd is not in the tar ball.  When I 
install the dtd in test/dtd/4.1.2 the test passes:

# /cluster/uapp/Libxml-2.5.11/bin/xmllint --noout --relaxng \
  test/relaxng/tutorA.rng test/relaxng/docbook.rng
test/relaxng/docbook.rng validates

I have to guess that the docbook zip file should be installed in 
test/dtd/4.1.2 fot the tests to work.

Under Relax-NG streaming regression tests docbook_0 fails similarly, but 
passes when dtd is in place.

I assume that the up to 10 line diffs further down in the streaming 
trests are within the scope of "Some error messages are different than 
non-streaming and generate small diffs".

All in all if the INSTALL document mentions the issue with installing 
ther docbook dtd, or if it is bundled in the tar ball this would be OK.
