In PyYAML tag types are mapped to python types (http://pyyaml.org/wiki/PyYAMLDocumentation#YAMLtagsandPythontypes) In contrast, in Markdown Meta-Data extension, values are strings (https://pythonhosted.org/Markdown/extensions/meta_data.html). The BaseLoader class only construct basic Python objects: lists, dictionaries and Unicode strings so will likely perform more as expected.

This extension adds YAML meta data handling to markdown.
