[xml/sgml-pkgs] Bug#754424: libxml2: spurius parser error (regression in 2.9.1+dfsg1-4)

[Vincent Lefevre]

Package: libxml2
Version: 2.9.1+dfsg1-4
Severity: important

On the attached file, I get the following error:

$ xmllint --noout mathml.xsl
mathml.xsl:45: parser error : Entity 'InvisibleTimes' not defined
  <xsl:if test="not(contains('⁢)',$text)) and
                                              ^
mathml.xsl:45: parser error : Entity 'rpar' not defined
  <xsl:if test="not(contains('⁢)',$text)) and
                                                    ^
mathml.xsl:48: parser error : Entity 'InvisibleTimes' not defined
  <xsl:if test="not(contains('⁢(',$text)) and
                                              ^
mathml.xsl:48: parser error : Entity 'lpar' not defined
  <xsl:if test="not(contains('⁢(',$text)) and
                                                    ^
mathml.xsl:71: parser error : Entity 'InvisibleTimes' not defined
  <xsl:if test="$text != '⁢'">
                                          ^

I had no such problem until 2.9.1+dfsg1-3, and downgrading makes
the error disappears.
