I don't quite understand this whitespace issue. (1) <mtext>Theorem 1: </mtext> is equivalent to (2) <mtext>Theorem 1:</mtext> Section 2.3.5 says that if you want to have whitespace uncollapsed, then you must use entities to escape it. (3) <mtext>Theorem 1:&x20;</mtext> won't work because to an SGML processor (1) and (3) are equivalent. So this seems to leave (4) <mtext>Theorem 1:&Space;</mtext> as our only option. This means that the DTD can't use (5) <!ENTITY Space ' '> because then (4) would become the same as (1). So the entity Space has to be define as something else. But I'm a little unsure what. Perhaps the best approach would be to define an SDATA entity. The SGML process can turn the SDATA into a space after trimming the whitespace from the element. (I actually don't know much about SDATA, but it's use here seems appropriate) Does anyone have any comments to clarify the issue? -- Russell O'Connor roconnor@uwaterloo.ca <URL:http://www.undergrad.math.uwaterloo.ca/%7Eroconnor/> "And truth irreversibly destroys the meaning of its own message" -- Anindita Dutta, "The Paradox of Truth, the Truth of Entropy"Received on Saturday, 21 March 1998 13:37:38 GMT
