XML naming rules for parameter and data names

Application parameter names, action parameter names, and data names should respect the XML naming rules listed below. Otherwise, the parameters and data will be saved as usual, but you might encounter issues if, for example, you try to export a process instance list when using the SOAP API XML RSS output.

  • They should begin with a letter or an underscore;

  • They should contain only letters, digits, hyphens, underscores, and periods;

  • They should not contain spaces; and

  • They should not begin with the letters XML in any case (e.g. xml or Xml).
