DrawingML is unrelated to the other [[vector graphics]] formats such as [[Scalable Vector Graphics|SVG]]. These can be converted to DrawingML to include natively in an Office Open XML document. This is a different approach to that of the [[OpenDocument]] format, which uses a subset of SVG, and includes vector graphics as separate files.

A DrawingML graphic's dimensions are specified in English Metric Units (EMUs). It is so called because it allows an exact common representation of dimensions originally in either English or Metric units—defined as 1/360,000 of a [[centimeter]], and thus there are 914,400 EMUs per [[inch]], and 12,700 EMUs per [[point (typography)|point]], to prevent round-off in calculations. [[Rick Jelliffe]] favors EMUs as a rational solution to a particular set of design criteria.<ref>{{ cite web |datetitle=AprilWhy 16, 2007EMUs? |authorlast1=Jelliffe |first1=Rick Jelliffe in Technical | url = http://www.oreillynet.com/xml/blog/2007/04/what_is_an_emu.html | title website= Why EMUs? - O'Reilly XML Blog | publisher = Oreillynet.comO'Reilly | access-date = 2009-05-19 |archive-url=https://web.archive.org/web/20141229020130/http://archive.oreilly.com/pub/post/what_is_an_emu.html |archive-date=2014-12-29 |url-status=dead}}</ref>

Some have criticised the use of DrawingML (and the transitional-use-only [[Vector Markup Language|VML]]) instead of [[World Wide Web Consortium|W3C]] recommendation [[Scalable Vector Graphics|SVG]].<ref>{{ cite web | url=http://reddevnews.com/features/article.aspx?editorialsid=2356 | title= The X Factor | publisher=reddevnews.com |date=October 2007 }}</ref> VML did not become a W3C recommendation.<ref>{{ cite web | url = http://www.w3.org/TR/NOTE-VML | title = VML&nbsp;— the Vector Markup Language | publisher = W3.org | date = 1998-05-13 | access-date = 2009-05-19 }}</ref>
