resetting appropriately:

• if current node is in the mathml namespace and is one of <mi>, <mo>, <mn>, <ms>, <mtext>, "in math content"
• if current node is in the mathml namespace, "in math"
• if current node is in the svg namespace, "in svg"

"in body":

• "math" element - switch to "in math"
• "svg" element - switch to "in svg"

"in math":

• comment
  1. insert comment

• doctype
  1. parse error

• text:
  1. imply <mtext>
  2. reprocess

• start tag for: <mi>, <mo>, <mn>, <ms>, <mtext>
  1. insert element for token
  2. switch to "in math content"
  3. if the tag had a closing slash, imply a closing tag with the same tag name

• start tag for one of: maction maligngroup malignmark menclose merror mfenced mfrac mglyph mlabeledtr mmultiscripts mover mpadded mphantom mprescripts mroot mrow mspace msqrt mstyle msub msubsup msup mtable mtd mtr munder munderover none
  1. insert element for token
  2. if the tag had a closing slash, imply a closing tag with the same tag name

• other start tag:
• end tag:
  or
  :
  1. parse error
  2. pop until <math> element is popped
  3. reset insertion mode
  4. reprocess

• other end tag
  1. if current element has the tag name of the token: pop it
  2. otherwise: if there is a matching element in scope and it has the mathml namespace: parse error, ignore token
  3. otherwise:
     1. parse error
     2. pop until <math> element is popped
     3. reset insertion mode
     4. reprocess

"in math content":

• start tag for one of: mglyph malignmark
  1. insert element for token
  2. if the tag had a closing slash, imply a closing tag with the same tag name

• end tag:

1. if the token is an end tag token and the current node is in the mathml namespace and matches the tag name of the token, pop the current node, and reset the insertion mode.
2. otherwise, treat as "in body"

• otherwise

1. treat as "in body"
