mrScriptMetadata has these types of names:

Names must conform to the mrScriptBasic rules for regular identifiers: see Naming conventions.

Names can be any of the reserved keywords: see Keyword summary.

There are additional rules for field and category names:

Some field names are reserved for the definition of standard messages: see Custom message texts.

The field name HDATA is reserved for setting labels, custom properties, styles, and templates on the document.

You can enclose field names in " " (quotation marks) to escape keywords, for example: "Column".

Category full names must be unique within the question.

You can enclose field names in " " (quotation marks) to escape keywords, for example: "Column".

The label is typically the question or category text that is displayed to the respondent.

The percent symbol (%) is an escape character, which allows you to give the characters that directly follow the percent symbol an alternate meaning. You can use the following character combinations:

Some characters have special meanings in HTML. For example, < indicates the start of a tag. If you want to use these characters in labels, you must replace them with codes, so that mrScriptMetadata does not read them as HTML characters. These are some common characters that must be encoded:

Characters that are actually used as tags in well-formed HTML do not require encoding. To create well‑formed HTML, make sure that there is an opening tag and a closing tag, and that tags are properly nested.

You can also add text insertions to the label, for example, to include the answer to a previous question: see Label text insertion.

If you do not specify a label, it will be the same as the field or category name.

By default, the label is in the default language, user context, and label type defined for the metadata section. However, you can optionally specify a different language, user context, and label type: see Alternative labels.
