Recent Issue with Anaconda

There is currently a bug in the libxml2 library version 2.9.4 installed by Anaconda 2.4.0 which is used in the SentThree's L3_XmlParser.py module for reading and validating XML config L3_GIPP.xml. Even though the XML files are correct, they are not properly validated as such by the XML parser due to this bug. Details are described here: https://bugzilla.gnome.org/show_bug.cgi?id=766834

If you are confronted with an error like:

Syntax error in metadata, see report file for details.
Parsing error:
Schema file: L3_GIPP.xsd
Details: Element 'PSD_Scheme', attribute 'PSD_Version': [facet 'length'] The value '' has a length of '0'; this 	differs from the allowed length of '2',

the solution is to downgrade the libxml2 library to the version 2.9.2 which is not affected by the bug. This is done by the following command:

conda install libxml2=2.9.2
