I'm going to copy-paste the Spell Glyph section from Glyph of Warding off the hypertext d20 SRD here:
Spell Glyph
You can store any harmful spell of 3rd level or lower that you know. All level-dependent features of the spell are based on your caster level at the time of casting the glyph. If the spell has a target, it targets the intruder. If the spell has an area or an amorphous effect the area or effect is centered on the intruder. If the spell summons creatures, they appear as close as possible to the intruder and attack. Saving throws and spell resistance operate as normal, except that the DC is based on the level of the spell stored in the glyph.
Glyph Seal stats that it converts any arcane or divine spell into a glyph similar to Glyph of Warding, and that it is triggered as the Spell Glyph function of Glyph of Warding.
Glyph Seal contradicts the Spell Glyph in a few ways: It allows divine spells (Glyph of Warding is normally an arcane spell and not a divine one), it allows ANY spell (explicitly stated), and the level of spell allowed is lower than Glyph of Warding normally permits.
Where Glyph Seal remains in line is that they are triggered the same way - either by an object (such as a door, or chest, or box, or drawer) being opened, or by a protected area being traversed (entering a warded area or passing a warded object) - and the targetting states that if the spell has a target, it targets the the intruder, or centers an area on the intruder, or summons a creature next to the intruder. Whatever the type of spell, the glyph affects the creature (singular) which triggered it as appropriate for the spell. However, Glyph Seal is only similar to Glyph of Warding, not identical. As noted earlier, WotC Customer Service stated that this was not something that they had considered with the item, and I either expect it to be errata'ed along with the myriad of typos and errors in the text, or for it to be ignored completely.
So far it seems the only real issue people have is the Personal range spells. Now, I can understand why certain spells would be out of the question, such as Rary's Mnemonic Enhancer, Read Magic, Speak With <Plural Noun> and Shapechange. Similarily, Alter Self and Disguise Self are no-brainers. But Overland Flight? False Life? Entropic Shield?
This is why my DM is approving spells on a case-by-case basis. If he thinks a spell is too unbalancing, he will simply disallow it.
