Exchange the first paragraph of the description

The draw:text-areas attribute specifies a list of text areas. The text area is used to position and align the text. If no text area is specified, the area of the shape itself is used. If a second text area is available it is used for vertical text.

with

The draw:text-areas attribute specifies up to two text areas. If the attribute specifies one text area, this text area is used to position and align the text. If the attribute specifies two text areas, then the second text area is used if a style that is assigned to the text has a style:writing-mode attribute with value "tb-rl" or "tb". Otherwise the first text area is used.
If the draw:text-areas attribute is omitted, the entire area of the shape is used to position and align the text.

Add the following EBNF:

textareas::= textareasequence
textareasequence ::= textarea ( ' '+ textarea )?
textarea::= position ' '+ position ' '+ position ' '+ position
position::= formula | modifier | number
formula::= '?' name
modifier::= '$' integer
number::= sign? float | sign? integer
float::= fractional exponent? | integer exponent
fractional::= integer? '.' integer | integer '.'
exponent::= ( 'e' | 'E' ) sign? integer
sign::= '+'| '-'
integer::= [0-9]+
name ::= [^ ]+
------

Please note that this does allow only two text areas.

Section 17.224 draw:text-areas

Ed. Note As defined, the attribute is inconsistent and incomplete. It starts by saying we define a list of text areas. Then it says what happens if a second text area is present. Then we define how to define a text area. As a string? So, we don't have a list, or at least no mechanism for one, possibly assume up to two text areas, and don't define what values define a text area.

Sven Jacobi says:

textareas::= textareasequence?

textareasequence ::= textarea ( ' '+ textareasequence )*

textarea::= position ' '+ position ' '+ position ' '+ position

position::= formula | modifier | number

formula::= '?' name

modifier::= '$' integer

number::= sign? float | sign? integer

float::= fractional exponent? | integer exponent

fractional::= integer? '.' integer | integer '.'

exponent::= ( 'e' | 'E' ) sign? integer

sign::= '+'| '-'

integer::= [0-9]+

name ::= [^ ]+

Patrick: Yes, but the prose requires:

"If a second text area is available it is used for vertical text."

Noting that the first text area being for horizontal text is only by implication.

Nor it is clear how more than two areas (assuming the regex were extended to include what is said in the prose) are to be positioned.

If this is meant to simply specify the position of one or more text areas in some defined coordinate space (represented by a <draw:enhanced-geometry> element) then why don't we simply say that?

Sven Jacobi further replies:

"If text in a shape is drawn and there is no draw:text-areas element, then entire area of the shape is used.

If the draw:text-areas element is available, then with one exception the first text area is used. And this is the

exception, if the text is verical and if a second text area is available, the second text area is used.

I am not sure if it is sensible do to specify a limitation of 2 rectangles, I thought it is sufficient without."
