## Block text content containing a left angle bracket must be well formed XML.

If the un-escaped content of a fact with base type us-types:textBlockItemType, or a type equal to or derived by restriction of type 'escapedItemType' in a standard taxonomy schema namespace contains the "<" character followed by a QName and whitespace, "/>" or ">", then the un-escaped content must contain only a sequence of text and XML nodes.

The "<" character may appear in the text content of an XML element as "&lt;", "&#x3C;", "&#60;" or some other guise; when it appears, the content of the element will then be "un-escaped" for analysis. If "<"is followed by a QName and whitespace, then the content is tested for XML well-formedness.

The element name has no significance in this rule, only the base type. For example, although the name of an element in a standard taxonomy having base type textBlockItemType conventionally ends with the string "TextBlock", the reverse is not always true.

Example XBRL | Text After "un-escaping" | Valid
<eg:AcidityTextBlock> ph&lt;1.0 </eg:AcidityTextBlock> | pH < 1.0 | Yes. Without a QName the un-escaped content is not interpreted as markup.
<us-gaap:InventoryTextBlock contextRef="x"> Inventory&lt;BR> </us-gaap:IntentoryTextBlock> | Inventory<BR> | No
<us-gaap:InventoryTextBlock contextRef="x"> 3. &lt;b>Inventory&lt;/b> </us-gaap:IntentoryTextBlock> | 3. <b>Inventory</b> | Yes
<eg:BenchmarkTextBlock> The &lt;i>S&amp;amp;P 500&amp;reg;&lt;/i> Index </eg:BenchmarkTextBlock> | The <i>S&amp;P 500&reg;</i> Index | Yes

Some software applications may render the resulting content of the element as if it was embedded in an HTML 3.2 document, and well-formed XML is a prerequisite for well-formed HTML. Considering the status of the text as a kind of management assertion, well-formed XML is in the interest of the registrant because it decreases the likelihood of incorrect renderings.

HTML entity references such as &reg; must be doubly quoted as shown in the example above. Likewise, an XML entity reference such as &amp; will appear in the un-escaped text only if doubly quoted.

REMARK: In XML it is vital to distinguish the DOM from its various serializations. For a text block, the DOM node starts as an element with one child text node; exactly one. It is that child text node that you now treat as a string, wrap <body> and </body> around it, then re-parse and validate against edbody.dtd; the grammar for the % Flow entity is clear.

REMARK: By contrast, the content of a footnote according to XBRL 2.1 is any alternating sequence of text nodes and element nodes drawn with names in the xhtml namespace. The serialization does not (and cannot) matter. The additional constraint on footnotes imposed by EDGAR is that a footnote cannot just contain any old sequence of text and element DOM nodes. It has to be a sequence of DOM nodes that would be valid if they were the children of a body node instead. You do not read the footnote as a text node (that might have ampersands and angle brackets), as if it were itself a serialization. You take that sequence of DOM nodes, make them the children of a <body> node and validate.

REMARK: Only restrictions of the textBlockItemType are relevant because the base type xbrli:stringItemType is declared final in the XBRL 2.1 schema and cannot be extended.
