Issue #1549
closed
pulp_distribution.xml fails to conform to many of the XML recommendations and standards.
Description
The XML specification states that an XML document should include an XML declaration of which version of XML is being used[0], as well as the character encoding used in the document. The XML document we use does not do this[1][2]. The prolog (for example "") should be the first line of the document.
XML documents should be in a namespace[3], but ours is not. A namespace should be something along the lines of "<something xmlns:"http://somehost/with/our/schema\>...\</something>". Since we don't do that, we don't include a schema with our document, either. The schema is located at https://github.com/pulp/pulp_rpm/blob/1ebbd75e8b076fd5d00c95b91c1c1ad26006ed52/plugins/usr/share/pulp-rpm/pulp_distribution.xsd
