XML Schemas available under https://github.com/Pyrax/gtan-xsd These XML Schema Definitions (called XSD) can be used to get autocompletion and simple validation in Visual Studio for writing XML files. This currently includes schemas for resources (ACL & Meta) and for server's settings. Usage is of course not limited to Visual Studio, though in other IDEs you might not get any benefits like autocompletion. General usage It's as simple as including the following snippet in the root element of your XML: Code: xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://gtan.azurewebsites.net/schema/resource" xsi:schemaLocation="http://gtan.azurewebsites.net/schema/resource http://gtan.azurewebsites.net/schema/resource/meta.xsd" This snippet is only for Meta-XMLs. For the other type of XML files you need to replace the paths. You can find a list of these files, examples and further instructions on GitHub. Additional notes on Visual Studio Spoiler By default, Visual Studio disabled the automatic download of schema files. You can either active it in the settings or you can manually download the files and replace the second url in "schemaLocation" with the local path of the downloaded schema file. The setting can be found under "Tools > Options > Text Editor > XML": Then tooltips and autocomplete should appear. If not, try to hold STRG and click on the link ending with .xsd. This should trigger a manual download of the schema. Download If you need the files, they can be retrieved from GitHub: https://github.com/Pyrax/gtan-xsd Otherwise they can simply be referenced the former way under "general usage".
