in reply to Re^4: LibXML doesn't encode single or double quotes
in thread LibXML doesn't encode single or double quotes

I agree fully. 
name='foo's bar'         # Attribute's value is: foo's bar
name="foo's bar"         # Attribute's value is: foo's bar
name="foo's bar"              # Attribute's value is: foo's bar

<name>foo's bar</name>        # Text's value is: foo's bar
<name>foo's b&#97;r</name>    # Text's value is: foo's bar
<name>foo's b&#x61;r</name>   # Text's value is: foo's bar
